Abstract

A radial piston-type pump is disclosed which includes a non-rotating control pin projecting into a cup-shaped housing. A pivoted cylinder block having radial holes is arranged on the pin. As the cylinder block rotates, the holes are alternately connected with a suction line and a pressure line. A connecting channel is provided which leads from the radial outer area of the inside chamber of the housing to the suction line of the pump.
