Abstract (en)
A fixed cylinder type radial piston pump (1) with volume control apparatus is disclosed, in which volume control is possible by means of a variable aperture (38) carrying out opening control of a suction passage (22). For achieving continuous volume control in a large range, the radial piston pump (1) can provide two pump portions separated by an intermediate wall (60) and including a gate valve (62) in the other suction passage (22'). Without installing the intermediate wall (60), it is also possible to separate the two pump portions from each other by using a suction check valve (64).
