Abstract
A fluid pumping system comprises a reciprocable pump having a reciprocable member. A valving system controls the supply of fluid under pressure to the reciprocable member to bring about reciprocation of the member. In order to provide a much more compact unit, the valving system is arranged to be offset radially from the reciprocable member, yet is drivingly connected to the reciprocable member through a unique mechanism so that the valving system may switch states responsive to the stroke travel of the reciprocable member.
