Abstract

PURPOSE: To heighten the speed and pressure of a pump-motor, by providing an oil pressure pocket on the conjoined portions of a shoe retainer and the spherical contact face of a shoe retainer holding member and supplying pressurized oil to the oil pressure pocket.
CONSTITUTION: An oil pressure pocket 41b is provided on the conjoined portions of a shoe retainer 41 and the spherical concave sliding face 41a of a shoe retainer holding member and connected to a hydraulic pump 51 through an oil hole 35c, an annular groove 35b, holes 11a, 11b, 11c and an oil passage 12 so that pressurized oil from the pump 51 is conducted to the oil pressure pocket 41b and positively lubricates and cools the retainer 41 and the sliding face 41a of the holding member. As a result, the sliding portions are protected from seizure and partial wear and the speed and pressure of a pump-motor can be heightened.
