摘要： Rotary vane pumps include casings having asymmetrical cavities that accommodate a rotor. For a single pump chamber, one portion of the rotor abuts or nearly abuts the inner wall of the cavity at a single location while one portion of the rotor and the inner wall are not in contact with each other thereby defining a pump chamber. For a dual pump chamber embodiment, two diametrically opposed portions of the rotor abut or nearly abut the inner wall of the cavity while two portions of the rotor and inner wall are not in contact with each other thereby defining the two pump chambers. The two pump chambers are disposed on opposite sides of the minor axis of the cavity. The cavities of each pump are skewed so each pump chamber is larger in volume at the inlet end than at the outlet end.
摘要翻译：旋转叶片泵包括具有容纳转子的不对称空腔的壳体。对于单个泵室，转子的一部分在单个位置处邻接或几乎邻接空腔的内壁，而转子和内壁的一部分彼此不接触，从而限定泵室。对于双泵室实施例，转子的两个直径相对的部分邻接或几乎邻接空腔的内壁，而转子和内壁的两个部分彼此不接触，从而限定两个泵室。两个泵室设置在空腔的短轴的相对侧上。每个泵的空腔是偏斜的，因此每个泵室在入口端的体积大于出口端的体积。

摘要： A vane compressor includes a cylinder block, a cylinder chamber having an ellipsoidal inner wall, a rotor whose outer circumferential surface is provided with vane slots formed thereon, a drive source for the rotor, and vanes housed in the vane slots, respectively. The rotor is rotated by the drive source while the vanes are protruded from the vane slots by backpressure generated in backpressure spaces in the vane slots to contact end edges of the vanes with the inner wall of the cylinder chamber. The compressor further comprises a stop mechanism that makes the rotor stopped at a predetermined rotational position where a difference between a total volume of the backpressure spaces when operated and a total volume of the backpressure spaces when stopped becomes minimum. According to the compressor, chattering can be prevented without extra workings on the vanes or the rotor and without providing extra parts.

摘要： A gas compressor includes a housing with suction and discharge ports, and a gas-compressing mechanism housed in the housing to compress a gas sucked through the suction port and discharge the compressed gas via the discharge port. The mechanism includes a cylinder defining a cylinder chamber with a circular or elliptical cross-sectional shape. The cylinder has a suction inlet and a discharge outlet. The suction inlet and the discharge outlet are opened in a peripheral wall of the cylinder chamber. A suction passage is formed along an outer periphery of the cylinder corresponding to a peripheral direction of the cylinder chamber. A discharge passage extends inside a thick portion of the cylinder along a center axis of the cylinder chamber. The suction inlet communicates with the suction port via the suction passage. The discharge outlet communicates with the discharge port via the discharge passage.

摘要： A first member is configured to undergo sliding contact with a surface of a second member. The surface of the first member is roughened by irradiating the surface of the first member with a laser to form first recesses in the surface of the first member. The surface of the first member is then cleaned followed by a finely roughening step of irradiating the first recesses formed in the surface of the first member with a plasma to form second recesses which are shallower than the first recesses. Thereafter, a fluorocarbon resin is coated on the surface of the first member so that the fluorocarbon resin securely contacts and adheres to the surface of the first member due to the rough and clean state thereof. The surface of the first member is then subjected to a heat treatment.
