摘要： An electromagnetic valve, which is provided between an intake port of a compressor body and a pneumatic line at an intermediate position of an intake pipe, is opened/closed by a control unit. Communication between the intake port of the compressor body and the pneumatic line is permitted when the valve is open, and is blocked when the valve is closed. In a start-up control of the compressor body, the electromagnetic valve is opened, permitting communication of the pneumatic line in the plant with the intake port of the compressor body for power supply to an electric motor to drive an orbiting scroll. Rattling of the orbiting scroll by an amount equal to the axial gap (play) is suppressed before starting a compression operation.

摘要： In a seal system for a scroll type fluid machine, a seal mechanism is provided between a backpressure plate and a holder, so as to surround an orbiting backpressure chamber. The seal member comprises a seal attachment groove, a seal member and a Y-shaped packing. The seal attachment groove is stepped on its outer circumference to define a shallow bottom portion. The seal member includes, on its outer circumference side, a cutout portion matching the shallow bottom portion. The Y-shaped packing is disposed between a deep groove peripheral wall of the seal attachment groove and the cutout portion of the seal member, and a backpressure chamber is defined on a reverse surface side of the seal member. By this arrangement, a slide surface of the seal member can be larger than an effective area of the backpressure side of the seal member. Thereby it is possible to reduce a difference between a load Ff acting on the slide surface and a load Fb acting on the reverse surface.

摘要： A scroll fluid machine having a lubrication pump provided between sliding contact surfaces of an orbiting scroll member and a thrust bearing in a casing. The pump has an orbiting member accommodating recess provided in the sliding contact surface of the thrust bearing. An orbiting member projects from the sliding contact surface of the orbiting scroll member into the recess. A slide plate defines a suction chamber and a discharge chamber in the recess. As the orbiting scroll member orbits, the orbiting member orbits in the recess, causing a lubricant contained in the casing to be sucked from a suction passage and delivered to the inside of a boss portion accommodating an orbiting bearing.

摘要： The invention reduces a centrifugal force of a orbiting scroll which acts on an auxiliary crank mechanism. A crank pin which is eccentric from a main shaft portion is formed in a drive shaft, and a main balance weight is provided in a base end side of the crank pin. The main shaft portion of the drive shaft is rotatably supported by using a main bearing, and the crank pin is attached to a orbiting bearing which is provided in a back face side of a orbiting scroll. Further, an internal gap of the main bearing is set to a value which is larger than a value obtained by subtracting the double value of an eccentric amount difference between an eccentric amount of an auxiliary crank shaft and an eccentric amount of the drive shaft from an internal gap of the orbiting bearing. Accordingly, the internal gap of the main bearing does not come to 0 even if a compressor comes to a steady state.
