Definitions
- the invention relates to a pulsation damper for damping pressure medium vibrations in a hydraulic system, in particular in a slip-controlled motor vehicle brake system, according to the preamble of claim 1.
- a pulsation damper for damping pressure medium vibrations in a hydraulic brake system for which the pulsation damper has a membrane within a bore of a housing, which is exposed to the pressure medium on one side, while the other side of the membrane is a cavity filled with a gas within the Housing faces, the bore of which is closed by means of a plug.
- FIG. 1 shows a schematic sectional illustration of a pulsation damper which is provided with a rubber membrane which has several transverse grooves on the outer circumference
- Fig. 2 is a sectional view of a further embodiment of the
- Pulsation damper the rubber membrane of which is provided with longitudinal grooves on the outer circumference
- FIG. 3 shows a sectional view of a further embodiment of the pulsation damper, which has a metal membrane
- FIG. 4 shows a sectional view of a pulsation damper, the membrane of which is fixed to a support body which is connected in one piece to a plug that closes the housing,
- FIG. 5 shows a sectional illustration of a pulsation damper, the membrane of which surrounds the stopper in the region of its tubular section.
- Figures 1 to 5 show useful embodiments of various pulsation dampers in longitudinal section, which are used for damping pressure medium vibrations in a hydraulic system, in particular in a slip-controlled motor vehicle brake system.
- the bore 13 provided for receiving the pulsation damper is closed in all embodiments by means of a plug 2, whereby, according to the invention, the membrane 1 in connection with the plug 2 and a hollow cylindrical support body 3 forms a compact, independently manageable, functional pre-testable assembly, for which the membrane 1 in Is designed essentially cup-shaped, in which the support body 3 extends.
- the membrane 1 is made of a permanently elastic material, in particular rubber or metal, while the plug 2 is made by cold extrusion or machining of a free-cutting steel. Furthermore, the membrane 1 is provided with either a plurality of grooves 18 or longitudinally extending ribs 19 along the outer circumference.
- the support body 3 in FIGS. 1 to 3 is penetrated by a channel 4 into which a check valve 6, which is acted upon by a compression spring 5 and opens on the outlet side, is inserted. Furthermore, it can be seen from FIGS. 1 to 3 that, parallel to the check valve 6, a fixed screen 7 is arranged in the channel 4, which is preferably designed as a notch in the area of a valve seat 8 provided for the check valve 6 in the channel 4.
- the channel 4 has a radial inlet area 9 and an axial outlet area 10 in the support body 3, the fixed diaphragm 7 and the check valve 6 opening in the direction of the outlet area 10 for effective vibration damping in the outlet area 10 of the channel 4 are arranged.
- the plug 2 has a sleeve-shaped section 11 in which the pot-shaped membrane 1 is completely received, so that the gas-filled flea space 12 is formed in a simple manner between the outer surface of the membrane 1 and the inner surface of the sleeve-shaped plug 2. Since the membrane 1 is securely fixed at its end facing away from the stopper 2 on the sleeve-shaped section 11 with the aid of the support body 3, the gas-filled flea space 12 is hermetically separated from the pressure medium within the bore 13.
- the support body 3 has a collar 14, which is connected to the sleeve-shaped section 11 in a force-locking manner for secure fixing and sealing of the gas-filled flea space 12.
- the check valve 6 in connection with the fixed diaphragm 7 is not integrated in the support body 3 in FIG. 4, since the support body 3 is formed in one piece directly on the plug 2, so that the membrane 1 is directly on the collar 14 of the support body 3 is fixed and is thus inserted as a pre-assembly component with the plug 2 directly into the bore 13 of the block-shaped housing 15.
- the volume-absorbing element, and thus the element damping the pulsations, is thus formed by an elastic membrane 1, which is filled with gas in the cavity
- the spring-loaded check valve 6 which releases a large cross-section for outflow from a defined pressure of the pressure medium to be damped. Until the defined pressure is reached, the pressure medium flows through the fixed orifice 7 structurally formed in the valve seat 8 of the support body 3 (or in the tappet-shaped check valve 6) past the closed check valve 6. Pressure pulses that are not sufficiently high to open the check valve 6 are absorbed by the elasticity of the membrane 1 and released again when the pressure drops. The pressure surges caused by the pressure generator / pump are divided and partially diverted into the damping chamber. The volume flow to the consumer is more even and the components are less stimulated to vibrate. In connection with the channel 4, the support body 3 directs and divides the Volume flow in such a way that an outflow without passing through the fixed diaphragm 7 is not possible.
- the sealing of the membrane 1 with respect to the bore 13 and to the support body 3 takes place in the radial direction.
- the support body 3 is provided with a particularly deep-drawn collar 14 if desired or required (see Figure 2) and seals the sleeve-shaped section 11 on the outer circumference against the pressure medium (operating medium) so that the pressure medium does not come into contact with the sleeve material and thus a possible chemical reaction of the pressure medium (e.g. brake fluid) on contact with zinc-containing surfaces is avoided.
- the pressure medium e.g. brake fluid
- the integration of the fixed diaphragm 7 and the check valve 6 in the support body 3 reduces the effort for the arrangement of the channel bore in the housing 15 and the closure cover or balls required for this.
- the peg-shaped design of the support body 3 enables an optimal flow to the membrane 1 and a flow deflection as well as an optimal outflow for the pressure medium.
- the support body 3 ensures the secure sealing of the gas volume against the operating medium as well as a secure assembly of the membrane 1 and prevents the membrane 1 from turning inside out when the system is filled with vacuum.
- the support body 3 creates the possibility of easily integrating the fixed diaphragm 7 and the check valve 6 and of checking the preassembled assembly outside the housing 15 for proper function.
- FIG. 5 shows another useful embodiment of a pulsation damper, the membrane 1 of which has a sleeve-shaped extension 20 which completely encloses a tubular section 11 of the plug 2 along its outer circumference, the end of the extension 20 between the section 11 and the Housing 15 is fixed under radial prestress. This results in a complete coverage of the within the bore 13 Plug 2 through the membrane 1, so that chemical reactions of the plug material, as a result of the separation from the brake fluid, do not occur. Furthermore, a plurality of ribs 19 are provided on the circumference of the membrane 1 between the section 11 and the cup-shaped area of the membrane 1, which ribs run in the longitudinal direction, so that the rigidity of the membrane 1 can be adjusted via their design.
- FIG. 5 The other details of the check valve 6 shown in FIG. 5 essentially correspond to the described FIGS. 1 to 3, but with the special feature that the support body 3 with the check valve 6 is arranged separately in the housing 15.
