Abstract

The motor has a piston (4) working in a cylinder (5). A reversing rod (12) is displaced by the piston every time it reaches one end of its movement, and carries a valve slide (9). The valve slide can also slide laterally within a recess in the top (11) of the reversing rod (12). This movement is effected by an auxiliary piston (13) perpendicular to the axis of the motor. The auxiliary piston is moved by fluid admitted to its end by ports (18, 19) uncovered by the valve slide (9). There is an elastic end stop (36) against which the reversing rod (12) presses at one end of its movement. This allows sufficient free movement to prevent the reversing rod moving the auxiliary piston prematurely.
