ABSTRACT:
A motor-driven radial plunger pump has an outer housing enclosing a motor section and a pump section drivingly connected thereto. The motor section has a motor housing cooperating with the outer housing to define a fluid passage having a fluid inlet adjacent to a part of the motor housing in which a brush unit is disposed. The fluid passage contains a filter element and has a recess disposed upstream thereof and adjacent to motor magnets so that magnetic particles contained in the fluid flow are magnetically adhered to and deposited on the bottom of the recess. The pump section has a rotor with radial plungers slidably disposed in cylinder bores in the rotor. The cylinder bores have radially inner end successively communicated with a suction passage communicated with the fluid passage between the outer and motor housings through feed holes formed in a coupling disc plate drivingly connecting the motor with the rotor. The feed holes each have a trailing side providing a face extending an angle of attack relative to the plane of the coupling disc plate whereby, when the disc plate is rotated with the rotor, the feed holes operate to positively feed the fluid into the suction passage.
