Swash plate type axial piston pump

Abstract

Abstract PURPOSE:To simplify the structure by letting the synchronized rotation drive of both a cylinder barrel with a cylindrical hole and rocking plate be performed by a drive rod. CONSTITUTION:When a drive shaft 1 is rotated, a cylinder barrel 2 is rotated so as to let a rocking plate 3 be rotated while being synchronized with a tilting plate 6 via a drive rod 5 for reciprocating a piston 4 to the shaft direction. The change of tilt angle allows a ball head 17 to move freely along a driving groove 20 so as to be identical with the pitch circle of a drive hole 21, the synchronized rotation is thereby possible correspondingly to the change of tilt angle. This constitution thereby enables the structure to be simplified without impairing the piston performance, thereby enabling the synchronized rotation positively.
