Definitions

  • the invention relates to a rotary piston machine with a fixed housing and an eccentrically arranged rotor, the peripheral wall of which touches the inner wall of the housing in one area, with at least one plate piston which is displaceably arranged in the rotor and is sealingly acted against the inner wall of the housing, and a front one Entry and compression space separates from a rear ignition and expansion space, and with an overflow space in order to transfer the medium compressed in front of the plate piston to the contact area of the rotor and housing for the ignition following the contact area behind the plate piston.
  • Such a rotary lobe machine can be found, for example, in FR 13 84 755 A. It is proposed there to form at least one overflow space in the rotor through the receiving slot for a plate piston, and to provide in the plate piston a valve element which can be pivoted to a limited extent and which alternately closes inlet and outlet windows in the plate piston.
  • the pivotable valve element is controlled by means of the pressure differences in front of and behind the plate piston.
  • Two such plate pistons are preferably provided offset by 180 °.
  • the invention has now set itself the task of creating an overflow space in such a rotary piston machine, which is not formed inside the rotor, and this is achieved in that the overflow space is formed by an expansion of the compression space in front of the contact area and one behind the Plate piston in the rotor slidably engages auxiliary piston sealingly engages in the overflow space.
  • the plate piston reaches the overflow space, it loses its sealing function as the rear end of the compression space, so that the medium which has already been partially compressed can emerge and is collected and further compressed by the auxiliary piston taking over the sealing function.
  • Expansion of the housing inner wall is formed, the width of which is smaller than that of the plate piston and possibly of the auxiliary piston, and that in the auxiliary piston one against Expansion of the housing inner wall spring-loaded slide is provided.
  • Sealing of the auxiliary piston is subject to the same criteria as the sealing of the auxiliary piston
  • the medium compressed to a maximum between the auxiliary piston and the plate piston is preferably in one
  • Inclined circumferential recess of the rotor in which the ignition then takes place as soon as the plate piston has entered the ignition and expansion space that opens in front of the contact area.
  • the volume of the circumferential recess is preferably adjustable.
  • auxiliary piston is preferably drawn in in the ignition and expansion space and in the start area of the inlet and compression space in the rotor, a very large ratio between the ignition and expansion space is achieved, for example around 1:40.
  • the pressure of the burned gases is therefore used much longer and better.
  • FIG. 8 shows a third embodiment with two pistons and an approximately oval housing
  • FIG. 9 shows a detail of a further embodiment.
  • the rotary piston machine shown in FIGS. 1 to 3 in different positions has an essentially cylindrical housing 1, in which a cylindrical rotor 6 is arranged eccentrically so that its periphery touches the inner wall 4 of the housing 1 at one point.
  • the area of contact is number 15 designated.
  • a plate piston 7 is arranged radially displaceably, which is pressed by a spring 8 to the inner wall 4 of the housing 1 in a sealing manner.
  • the plate piston 7 divides the rocket-shaped space between the rotor 6 and the housing 1 into a compression space 16 and an ignition and expansion space 17, the volumes of which change.
  • an extension 5 is provided in the compression space 16 in the form of an expansion in the housing inner wall 4, which cannot be filled by the plate piston 7.
  • the widening is narrower than the plate piston 7, so that the compressed medium flows outside the plate piston 7 to the rear.
  • an auxiliary piston 9, which is acted upon by a spring 13, is slidably arranged behind the plate piston 7 in the rotor 6. 4 and 5, the auxiliary piston 9 is shown in more detail. Since the auxiliary piston 9 must already bear sealingly against the inner wall 4 of the housing 1 when the plate piston 7 enters the area of the extension 5, the latter has a contour that is the same as that of the plate piston 7.
  • a slide 11 with the action of a spring 19 is provided in the auxiliary piston 9, the end region protruding from the auxiliary piston 9 taking over the sealing of the space formed between the plate piston 7 and the auxiliary piston 9 to the rear.
  • the overflowing medium is therefore compressed by the auxiliary piston 9 upon further rotation.
  • a circumferential recess 10 is formed in the rotor 6, which corresponds to the volume of the maximally compressed medium, which, enclosed in the circumferential recess, passes the contact area 15 and is ignited in the ignition chamber 17.
  • the auxiliary piston 9 remains drawn into the rotor 6, so that the expansion space can reach a maximum size.
  • the auxiliary piston 9 is retained in the rotor 6 one curved groove 12 each extending at least over 180 ° in the two
  • Guide slots of the plate piston 7 and of the auxiliary piston 9 in the rotor 6 are preferably connected to one another by internal air compensation channels and to a larger cavity in the rotor 6 which may be provided.
  • FIGS. 6 and 7 differs from the described embodiment according to FIGS. 1 to 3 only in that two diametrically opposed plate pistons 7 are provided in the rotor 6, which are pressed apart by a preferably common central spring 8.
  • An auxiliary piston 9 is assigned to each plate piston 7, and between the plate piston 7 and the auxiliary piston
  • FIG. 8 shows an approximately oval housing 1, in which the cylindrical rotor 6 is arranged centrally. 6 and 7, two plate pistons 7 and two auxiliary pistons 9 are arranged in the rotor 6, as are two circumferential recesses
  • FIG. 9 shows a further embodiment in which the volume of the circumferential recess 10 of the rotor 6 can be changed.
  • the bottom of the depression is formed on an insert 19 that is adjustable in the rotor, wherein the actuator 20 can be carried out hydraulically or mechanically.

Abstract

La présente invention concerne une machine à piston rotatif comprenant un boîtier fixe (1) et un rotor (6) disposé de manière excentrée dans le boîtier (1), la paroi périphérique dudit rotor étant en contact dans une zone (15) avec la paroi interne (4) du boîtier (1). Ladite machine présente un piston plat (7) disposé de façon à pouvoir se déplacer dans le rotor (6), ledit piston plat appuyant de façon étanche contre la paroi interne (4) du boîtier (1). Le piston plat (7) sépare une chambre avant d'admission et de compression (16) d'une chambre arrière d'allumage et d'expansion (17). Ladite machine présente également une chambre de trop-plein servant à acheminer le liquide comprimé à l'avant du piston plat (7) jusqu'à la zone de contact (15) entre rotor (6) et boîtier (6), à l'arrière du piston plat (7) pour permettre l'allumage ayant lieu de ce côté de la zone de contact (15). La chambre de trop-plein est formée par une extension (5) de la chambre de compression (16) à l'avant de la zone de contact (15). A l'arrière du piston plat (7) se trouve un piston auxiliaire (9) disposé de manière à pouvoir de déplacer dans le rotor (6) et appuyant de manière étanche vers l'arrière contre la chambre de trop-plein.
