Abstract (en)
[origin: US5354181A] Hydraulic piston pump driven in an alternating reciprocating motion by bearing, through a stud, against a cam carried by a drive shaft, characterized by the fact that a device acting as non-return feed valve is incorporated in each piston (14) while the discharge pressure is permanently re-injected into the interior of the stud (17) by which said stud (17) takes support on said cam (6).
