PROBLEM TO BE SOLVED: To provide a swash plate plunger hydraulic device of a simple structure, which can prevent occurrence of a surge pressure and a negative pressure by preventing sudden changes in the pressure within a cylinder and can reduce vibrations and noises. SOLUTION: A communication hydraulic path 31 branched from a delivery path 20 connecting with a delivery port 18 is opened on a distributor plate 7, and a pressure within the delivery path 20 is supplied to a cylinder hole before completion of the expansion stroke. On the other hand, a communication hydraulic path 33 branched from a suction path 21 connecting with a suction port 19 is opened on the distributor plate 7, and a pressure within the cylinder hole before completion of the compression stroke is emitted to the suction path 20.
