PISTON PUMP AND OPERATING METHOD THEREFOR

摘要

#CMT# #/CMT# The housing (10) has a bore receiving an eccentric shaft. Six cylinders (12-16) accommodate respective pump pistons that are connected with the eccentric shaft. The cylinders are disposed in pairs in three offset planes, where each cylinder opens onto the bore for the shaft. Linearly running fluid channels connect the three cylinders arranged on different planes. Distance between two adjacent planes is smaller than maximum diameter of one of the cylinders. Angular distance between the cylinders arranged in one plane is of 150 degrees within the plane. #CMT# : #/CMT# An independent claim is also included for a method for operating a hydraulic pressure generator in a vehicle braking system. #CMT#USE : #/CMT# Piston pump housing for a pump piston assembly of a hydraulic pressure generator in a braking system (all claimed) of a motor vehicle. Can also be used for an electro-hydraulic vehicle braking system, hydraulic brake force booster system, anti-lock braking system, interval control system, drive slip control system and an electronic stability program. #CMT#ADVANTAGE : #/CMT# The cylinders are disposed in pairs in three offset planes, where each cylinder opens onto the bore for the eccentric shaft, thus increasing operating comfort of the piston pump and improving the lifespan of the piston pump. The pump pistons are connected with the eccentric shaft, thus reducing the wear of the piston pump. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a piston pump housing. 10 : Piston pump housing 12-16 : Cylinders 18 : Front side.
