Abstract

In a pneumatic engine provided with a piston (2), a piston rod (3) and a piston slide parallel and capable for example of driving piston pump used for atomizing or spraying paints, the slide (13) is actuated by the piston rod (3) towards the end of each stroke of the piston (2) by means of an inversion device. The inversion device comprises an actuating member which effects a reciprocating motion between two stops (18, 19) fixed on the slide. In order to accelerate the inversion of the slide as well as to simplify and reduce the required force for the inversion of the slide, the inversion device comprises only one lever (21) of which the free end is connected to the piston rod (3) by means of a traction spring (29). This freed end of the lever (21) is the actuating member which give pulses to the slide (13) upon running against the stop (18, 19) with individual adjustment. The lever may be a handle supported on both sides and of which the central part forms the actuating member.
