FIELD: machine building.SUBSTANCE: axial-piston machine comprises control block with through lengthwise bores. Block outer cylindrical surface is fitted in bearings mounted in housing to engage with central output shaft. Pistons are arranged in opposition in said lengthwise bores on both sides. Said lengthwise bores are central part are communicated with block cylindrical surface by radial bores. Said radial bores can be communicated with distribution openings made in the body distribution ring that makes an integral part of the body and is arranged between block bearings fitted on both side of the body. Distribution openings are separated by blind sectors over the length of distribution ring inner hole. Sealing annular collars are arranged on sides of distribution rings. Distribution openings are communicated with working fluid inlet and outlet channels to make high- and low-pressure lines. Pistons partially extending beyond the block rest upon antifriction bearings mounted inclined to block rotational axis and fitted in covers secured at both sides of the housing.EFFECT: higher efficiency and rpm, simplified working fluid feed and discharge.3 cl, 3 dwg |
