Abstract

PURPOSE:To secure smooth movement and improve durability by arranging a multiplicity of static pressure pads symmetrically with respect to a certain axial line of a cross section perpendicular to a drive shaft to a bearing sleeve supporting the drive shaft freely rotatably via a bearing. CONSTITUTION:A piston 5 is fitted in each of a multiplicity of cylinder holes 2 board in a cylinder block 3 with its tilting angle being freely adjustable and a piston rod 4 of the piston 5 is pivoted on a drive disk 6B of a drive shaft body 6. A shaft 6A of the drive shaft body 6 is supported with a bearing sleeve 8 via a bearing 9. In this case, the bearing sleeve 8 is fitted to a housing cover 1. A static pressure bearing pad 16 having a throttle section 14 and a pressure chamber 15 is arranged in a chamber 13 formed on the opposite end of the drive disk 6B of the bearing sleeve 8 with a rod 17 of said pad 16 inserted in said chamber 13. The static pressure bearing pad 16 is provided in multiple number symmetrically with respect to a certain axial line of a cross section perpendicular to the drive shaft 6.
