Summary:23,069. Adolfsson, A. E. Oct. 5. Cam-actuated pumps with reciprocating and rotating pistons. - Relates to pumps having pistons which reciprocate and rotate simultaneously, act as the fluid-distributing valves, and have helical surfaces at each end which coact with rollers to effect the reciprocation. The improvement consists in joining the right and left hand helical surfaces by a flat surface C, Fig. 1, so arranged that, when the ports E, F of the piston do not register with the inlet and outlet openings in the cylinder G, the piston does not reciprocate.
