| To improve productivity and increase seizing resistance and abrasion resistance of a sliding surface of a tilt adjustment cylinder, a plurality of pistons are arranged cirumferentially in a cylinder block configured to rotate with a rotating shaft. Tip end portions of the pistons slide along the swash plate, and the pistons reciprocate. The swash plate is supported to tilt with respect to the rotating shaft. Further, a tilt adjustment driving portion is included. The tilt adjustment driving portion includes tilt adjustment large- and small-diameter cylinder chambers and tilt adjustment large- and small-diameter pistons configured to slide in the cylinder chambers to change the tilt angle of the swash plate. A sliding surface of the inner peripheral surface of each of the cylinder chambers includes a quenched portion formed by quenching using laser light, the sliding surface being a surface on which the tilt adjustment piston slides. | ||||||

| Embodiments of the present innovation relate to a cylinder bore coating system which simultaneously combines both friction and wear properties to enhance engine efficiency and operating life. The cylinder bore coating system includes a relatively thin top layer, such as diamond like carbon layer (DLC), disposed over a thicker, relatively hard and high modulus coating (i.e., an under coating). This combination of layers provides both low friction as well as low wear characteristics to the engine bore, relative to conventional engine bore coatings. | ||||||

| A compressor having a compression element with a cylinder in which a compression space is constituted, a suction port and a discharge port which communicate with the compression space in the cylinder, a support member which closes an opening on the cylinder and a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member. A compression member, whose one surface crosses an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and is disposed in the cylinder to be rotated by the rotary shaft, compresses a fluid sucked from the suction port to discharge the fluid via the discharge port. A vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member partitions the compression space in the cylinder into a low pressure chamber and high pressure chamber. A shaft seal which is disposed on an end portion of the main bearing, on a side opposite to the compression member, abuts on the rotary shaft. | ||||||
