초록 ▼

A hydraulic pressure booster includes a housing having a pump portion, a shaft portion and a turbine portion. The pump portion has a pump inlet and a pump outlet. The turbine portion has a turbine inlet and a turbine outlet. The turbine portion and pump portion are fluidically separated by the shaft portion. A shaft is supported by a bearing within the shaft support portion. The shaft extends between the pump portion and turbine portion and has a pump impeller and a turbine impeller located in its respective portion. The shaft defines an axis of the housing. A thrust load reducer is provided within the turbine portion to reduce axial thrust toward the thrust bearing.

1. A hydraulic pressure booster comprising:a housing having a pump portion, a shaft support portion and a turbine portion, said pump portion having a pump inlet, a pump outlet, said turbine portion having a turbine inlet and a turbine outlet; a rotor having a shaft, an pump impeller and a turbine impeller, said shaft defining a longitudinal axis of said housing; a center bearing positioned between said housing and said shaft, said center bearing rotatably coupling said shaft to said housing, whereby upon rotation of said rotor a thrust force along said longitudinal axis is generated; a thrust bearing having a groove in a thrust bearing face adjacent said turbine impeller and a channel fluidicaly couplgte turbine outlet and groove, said thrust bearing generating a force opposite to said thrust force; and a thrust load reducer within said turbine portion generating a a second force opposite to said thrust force.
