Abstract
PURPOSE: To make it easy to secure capacity and increase durabulity by the method wherein a pair of opposing plungers are fitted to plural through open cylinders arranged in a ring form, and thereby oil chambers are formed, and a pair of swash plates are arranged on each outer end of opposing plungers.
CONSTITUTION: Plural through cylinder holes 13 are arranged in a ring form on motor cylinder 12 of hydraulic motor M having output shaft 16 and supporting shaft 17 on its both end surfaces. A pair of opposing motor plungers 14l and 14r of the same diameter are fitted to each hole 13, and motor oil chamber 13A is formed among them. A pair of motor swash plates 27l and 27r are fitted to each outer end of motor plunger groups 14l and 14r. The inclinations of swash plate frames 31l and 31r, which support these, are simultaneously changed by the trunnion shaft via the coordinating device. Operating oil is supplied and discharged through linking port 39. Consequently, it is possible to secure a sufficient capacity by increasing the number of plungers without being influenced by the outer diameter of the motor cylinder, and further, it is possible to adjust the capacity by changing the inclination of each swash plate by a small angle, so that the durability of the equipment can be improved.
