ABSTRACT:
The radial piston or reciprocating engine (1) has annularly juxtaposed, radially directed piston-cylinder units (2, 3). The outward stroke of the pistons (2) is controlled by the cam (11) of a common eccentric shaft (12), whereas the inward stroke thereof is controlled by a control ring (16), which engages in a lateral recess (17) of each piston (2) running in the direction of a secant and adapted to a cross-sectional shape of the control ring (16). The recess (17) is then bounded by a base wall of the piston (2) with which the control ring (16) is in controlling sliding contact via an inner control face (20). The pistons (2) are hollow and carry on their face the diaphragm of a diaphragm valve. Thus, the reciprocating engine (1) has a particularly compact construction and can be highly loaded, so that it is particularly suitable as a compressor of a CO2vehicle air conditioning system.
