Abstract

Die Erfindung bezieht sich auf eine Kolbenmaschine mit einem Gehäuse (1), in dem eine Triebwelle (2) drehbar gelagert ist, auf der im Gehäuseinnenraum (1a) ein Zylinderblock (3) mit Zylinderbohrungen (8) angeordnet ist, in denen Kolben (7) durch einen Antrieb hin und her verschiebbar gelagert sind, wobei eine Dämpfungsvorrichtung (21) vorgesehen ist zur Dämpfung von plötzlich auftretenden Druckerhöhungen. Zwecks Gewährleistung einer kleinen Bauweise ist die Dämpfungsvorrichtung (21) durch ein Wandteil (22) der den Gehäuseinnenraum (1a) begrenzenden Gehäusewand (1b) gebildet, das bei einem Gehäuse-Innenraumdruck oberhalb eines bestimmten Druckwertes nach außen elastisch nachgibt.

The invention relates to a piston machine with a housing (1) in which a drive shaft (2) is rotatably mounted, on which a cylinder block (3) with cylinder bores (8) is arranged in the housing interior (1a), in which piston (7 ) are displaceably supported by a drive, a damping device (21) being provided for damping suddenly occurring pressure increases. In order to ensure a small construction, the damping device (21) is formed by a wall part (22) of the housing wall (1b) delimiting the housing interior (1a), which yields elastically to the outside at a housing interior pressure above a certain pressure value.
