Abstract

Die Hubkolbenmaschine (1) hat ringförmig nebeneinander angeordnete, radial gerichtete Kolben-Zylindereinheiten (2,3). Der Auswärtshub der Kolben (2) wird durch den Exzenter (11) einer gemeinsamen Exzenterwelle (12) gesteuert, während ihr Einwärtshub durch einen Steuerring (16) gesteuert wird, der in eine seitliche, in Richtung einer Sekante verlaufende, einer Querschnittsform des Steuerringes (16) angepasste Aussparung (17) jedes Kolbens (2) eingreift. Die Aussparung (17) wird durch eine Bodenwand des Kolbens (2) begrenzt, mit der der Steuerring (16) über eine innere Steuerfläche (20) in steuerndem Gleitkontakt steht. Die Kolben (2) sind hohl ausgeführt und tragen an ihrer Stirnseite die Membran eines Membranventils. Die Hubkolbenmaschine (1) hat somit eine besonders kompakte Bauweise und ist hoch belastbar, so dass sie sich besonders als Kompressor einer CO2-Fahrzeugklimaanlage eignet.

Figure imgaf001
The reciprocating engine (1) has ring-shaped juxtaposed, radially directed piston-cylinder units (2,3). The outward stroke of the pistons (2) is controlled by the eccentric (11) of a common eccentric shaft (12), while their inward stroke is controlled by a control ring (16) extending into a lateral, secant, cross-sectional shape of the control ring (16). 16) adapted recess (17) engages each piston (2). The recess (17) is bounded by a bottom wall of the piston (2) with which the control ring (16) is in sliding control contact via an inner control surface (20). The pistons (2) are hollow and carry on their front side, the membrane of a diaphragm valve. The reciprocating engine (1) thus has a particularly compact design and is highly resilient, so that it is particularly suitable as a compressor of a CO 2 vehicle air conditioning.
