The invention relates to a reciprocating piston engine for a liquid or gaseous working medium, with at least one piston performing a straight-line reciprocating movement in a cylinder, which piston in the cylinder separates a first piston chamber from a second piston chamber, and with a reversing device which, in the two limit positions of the piston, alternately connects a feed line for the working medium to the first or second piston chamber. In order to simplify the construction and improve the functioning, the following features are proposed: a) the first piston chamber is connected to a first control chamber by way of a first flow line, whilst the second piston chamber is connected to a second control chamber by way of a second flow line; b) the two control chambers have a reversing valve, which in its one limit position in the first control chamber connects the said feed line to the first flow line and in the second control chamber connects the second flow line to a discharge line for the working medium at zero pressure, and which in its other limit position in the first control chamber interrupts the said connection between feed line and first flow line and at the same time connects the first flow line to the said discharge line and in the second control chamber interrupts the said connection between second flow line and discharge line and at the same time ...
