#CMT# #/CMT# The device has an operating fluid pressurizing system (10) for lubrication, refrigeration and/or operation of a gearbox shift element. A separation unit (11) flow-technically separates a main pump (12) from the pressurizing system. The separation unit comprises a check valve, which prevents operating fluid flow (14) from the pressurizing system toward the main pump. The separation unit comprises a spring i.e. spiral spring, which independently moves the check valve to a closed position. A gearbox i.e. hybrid gear box, is coupled with an internal combustion engine (16) and an electromotor. #CMT#USE : #/CMT# Gearbox device for use in a hybrid power train of a hybrid motor car. #CMT#ADVANTAGE : #/CMT# The separation unit flow-technically separates the main pump from the operating fluid pressurizing system and comprises the check valve, which prevents the operating fluid flow from the pressurizing system toward the main pump, thus reducing operating fluid leakage with small pressure losses and reduced installation space of the device in an inexpensive manner, and avoiding a need of an additional pump so as to reduce carbon dioxide emission of the car. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a motor car gearbox device with a separation unit arranged in a pressure channel. 10 : Resource printing system 11 : Separation unit 12 : Main pump 14 : Resource flux 16 : Internal combustion engine. |
