  • Vane pump with a pump housing, in which a suction chamber is provided, and opening into the suction pump housing breakthrough, wherein in the pump housing breakthrough opening into the open or in an external vacuum space suction check valve is arranged, which is housed in a pot-shaped valve housing and the cup-shaped valve housing has a housing bottom and a housing shell.
  • a vacuum pump with such a structure has become known.
  • air is sucked out of a vacuum space, for example a brake booster, whereby the suction space inside the vacuum pump is formed by vane cells.
  • the vacuum pump is equipped with a suction check valve, which is arranged in a pump housing breakthrough.
  • This suction-check valve is sleeve-like and has a cup-shaped valve housing with a housing shell and a housing bottom, wherein the housing bottom is inserted into the pump housing of the vacuum pump.
  • the sealing of the suction check valve in the pump housing breakthrough takes place for example by means of sealing elements, for example O-rings.
  • a holding body is used in the housing shell of the suction check valve, which serves to hold the valve body.
  • suction-check valve in particular its valve housing, is constructed in several parts, and that the valve body is attached to a separate component, namely the holding body.
  • a fast and simple, especially automated, Assembly is made more difficult.
  • the invention is therefore an object of the invention to provide a vacuum pump, in particular a suction check valve, which or which has a simplified structure.
  • the invention thus relates to a vacuum pump or a suction check valve, wherein the housing bottom is not formed as a separate component, in particular as a holding body for the valve body, but is integrally connected to the housing shell.
  • integrally formed on the housing shell housing bottom forms a defined holding element for the valve body, so that it can take a defined and exact position.
  • no holding body has to be held in position by the valve body.
  • a simple automated assembly is therefore easily possible because the valve body of the suction check valve must be equipped only with the valve body, i. that the valve body only has to be inserted into the valve housing.
  • Valve housing on a receptacle for a holding portion of the valve body.
  • the holding portion of the valve body is attached to the receptacle, so that the valve body rests securely on the housing bottom and is thereby ensured that the valve body can completely close the valve openings located in the housing bottom or can release during the suction operation.
  • the receptacle is formed as a breakthrough.
  • the receptacle can completely penetrate the housing bottom, which has the advantage that the receptacle can be made relatively simple, for example in the form of a bore.
  • the assembly is thereby facilitated because the holding section only in the Recording must be inserted or plugged.
  • Recording has a hollow cylindrical, in particular a circular cylindrical, cross-section.
  • the receptacle is formed, for example, by a bore or punched into which a pin or knob-like holding portion, which also has a cylindrical cross-section, is inserted or inserted. A locking of the pin in the recording is not.
  • the receptacle according to the invention is formed undercuts, a simple automatic assembly can be done without locking connections or locking between the receptacle and the valve body must be made.
  • the valve body consists of an elastic, in particular rubber-elastic material, so that this completely conform to the openings in the housing bottom and can seal them. It is also conceivable to produce the valve body made of spring steel, optionally with a coating as a sealing element.
  • the bottom of the cup-shaped valve housing has a housing jacket over the housing bottom continuing edge and in the space formed by the housing bottom edge of a holding disc is pressed.
  • the retaining washer which is also penetrated by openings, forms a securing element which holds the valve element on the housing bottom.
  • the mounting of the retaining disk takes place only in that it is pressed into the intermediate space, which is surrounded by the edge, and thereby held captive.
  • the retaining disc has a slight excess and is deformed by the pressing and jammed in the space.
  • the valve element is arranged between the housing bottom and the retaining washer and is held by the retaining washer on the housing bottom.
  • the retaining washer presses the holding section into the receptacle of the housing bottom and thereby fixes the valve element.
  • Figure 1 shows a longitudinal section l-l according to Figure 3 by a

  • Figure 2 is a side view of the valve of Figure 1;
  • Figure 3 is a view in the direction of arrow III of Figure 2.
  • FIG. 4 shows a view in the direction of the arrow IV according to FIG. 2.
  • FIG. 1 shows an indication of a portion of a generally designated 10 pump housing of a vacuum pump 12, wherein 14 denotes the inner peripheral surface of a suction chamber 16.
  • a suction check valve 24 is used, on whose free end 26 a (not shown) suction hose can be pushed.
  • the suction check valve 24 shown in longitudinal section has a valve housing 28, which is cup-shaped and is formed essentially by a housing shell 30 and a housing bottom 32.
  • the housing jacket 30 extends beyond the housing bottom 32 into an edge 34, which projects beyond the housing bottom 32 on its opposite side.
  • the valve housing 28 is provided with a circumferential groove 36 into which a sealing ring 38, in particular an O-ring, is inserted.
  • the housing bottom 32 which can also be seen in Figure 3, is with
  • Openings 40 are provided which allow the overflow of air in the direction of the suction chamber 16. These breakthroughs 40 are on the Suction chamber 16 facing side of the housing bottom 32 covered by an elastic valve body 42 so that air can flow only in the direction of the suction chamber 16 when the valve body 42 lifts and the openings 40 are free.
  • the valve body 42 is constructed rotationally symmetrical and has a substantially conical cap 44 which covers the openings 40 and which is arranged on a central holding section 46, in the exemplary embodiment shown, a pin 47.
  • This pin 47 passes through a receptacle 48 in the housing bottom 32, wherein the receptacle 48 is formed as a circular cylindrical bore.
  • the receptacle 48 and the pin 47 are formed without undercuts, so that the pin 47 can be easily inserted into the receptacle 48 and pulled out of this again.
  • a holding element in particular a holding plate 50, which is pressed into the space surrounded by the edge 34 gap.
  • the retaining disc 50 thus has a slight oversize relative to the circumference of the space bounded by the edge 34.
  • the holding plate 50 also has openings 52, which can be seen from Figure 4, through which air can be sucked in the direction of the suction chamber 16.
  • the retaining washer 50 is pressed so far that its central region on the valve body 42 bears against the pin 47 and thereby holds the pin 47 in the receptacle 48.
  • Between the slightly conical housing bottom 42 and the retaining plate 50 is a sufficiently large space in which the cap 44 can be deflected when it is lifted from the openings 40 during the intake of air.
  • valve housing 28 with one-piece housing shell 30 and housing bottom 32 allows a quick and easy installation of the valve body 42 which is not latched to the housing bottom 32 and is held only by the retaining plate 50 on the housing bottom 32.
