CRABOTAGE DESYNCHRONISE D'UN APPAREIL HYDRAULIQUE

摘要

#CMT# #/CMT# The circuit has a hydraulic machine (2) i.e. radial piston hydraulic machine, including two ports designed to be connected to a high pressure line (HP) and a low pressure line (BP). One of the ports is a hydraulic fluid intake port (21), and the other port is a hydraulic fluid discharge port (22). A distributor (4) is designed to sequentially connect the ports of the hydraulic machine to the lines. A control line has pressure lower than pressure in the low pressure line. A connection unit selectively connects the ports to the control line. #CMT# : #/CMT# An independent claim is also included for a method for controlling a radial piston hydraulic machine. #CMT#USE : #/CMT# Hydraulic circuit for use in a transmission of a hybrid vehicle. #CMT#ADVANTAGE : #/CMT# The design of the circuit ensures progressive coupling, so that the impact on lifetime of the hydraulic machine is reduced without requiring a pump or dedicated pressure supply unit while reducing noise of the circuit. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a hydraulic circuit. BP : Low pressure line HP : High pressure line 2 : Hydraulic machine 4 : Distributor 21 : Hydraulic fluid intake port 22 : Hydraulic fluid discharge port.
