ABSTRACT:
A reciprocable device comprising a reciprocable member mounted for reciprocating movement within a chamber and a valve system for controlling the supply of fluid under pressure to the reciprocable member to bring about reciprocation of the member. The valve system comprises a spool valve, a coupling mechanism for joining the reciprocable member and the spool valve, and a bistable spring, which is actuated by the reciprocable member, for driving the spool valve through the coupling mechanism.
