Radial piston hydraulic pump, has skid whose one of plane lateral faces is arranged on adjusting gib which is pushed back against one lateral face of cam, where gib has longitudinal discharge groove in its lateral face supported against cam

摘要

#CMT# #/CMT# The pump (1) has radial pistons (2) whose each skid (20) presents plane lateral faces (200) contacting with two lateral faces (41) of a cam in a sliding manner. Two slide and support lips (201) of each skid is placed against a cam surface (40), and traversely extend to the plane faces. The lips, the plane faces and the cam surface delimit a volume receiving pressurized oil. One of the plane faces is arranged on an adjusting gib (210) which is pushed back against one of the lateral faces of the cam. The gib has a longitudinal discharge groove in its lateral face supported against the cam. #CMT#USE : #/CMT# Radial piston hydraulic pump. #CMT#ADVANTAGE : #/CMT# The discharge groove permits to limit a surface of the adjusting gib that is subject to the oil pressure, thus adjusting the pushing back of the adjusting gib against the cam, and hence limiting oil leakage and rupture of hydrostatic equilibrium of the skid, while limiting pressure force on a basal surface of the skid. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a radial piston hydraulic pump. 1 : Radial piston hydraulic pump 2 : Radial pistons 20 : Skid 40 : Cam surface 41 : Lateral faces 200 : Plane lateral faces 201 : Slide and support lips 210 : Adjusting gib.
