Abstract

PURPOSE:To enable oscillation with a small changeover force by connecting/ disconnecting a lubricating port which is opened to the rotatably supporting part of a swash plate to a cylinder bore through a cut-out part formed on a changeover piston. CONSTITUTION:Pistons 15 are linked to a swash plate 16, which can be oscillated to change over its angle by means of changeover pistons 18 provided in a housing 10. Oil ports 21, 22 are provided in the cylinder bores 19 of the changeover pistons 18 and cut-out parts 28 which are connected to lubricating ports 26, 27 are formed on the changeover pistons 18. Only when each changeover piston 18 is projected to its stroke end, a high pressure oil is fed to rotatably supporting parts through the cut-out parts 29 and lubricating oil ports, enabling oscillation with a small changeover force.
