A fluid pump consists principally of a housing with two or more parallel cylindrical pump chambers, in each of which a piston is reciprocally moveable. Each piston is connected via a piston-rod to a rocker-piece mounted on a parallel to the cylinders, rotatably journalled in the housing driving-shaft. The piston-rod is connected at one end firmly to the piston and at the other end movably to the rocker-piece, the piston-rod being at the piston end tiltable around a transverse axis in relation to the housing. |
