    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.

    摘要翻译： 在用于涡旋式流体机械的密封系统中，在背压板和保持器之间设置密封机构，以便围绕绕动的背压室。 密封构件包括密封附接槽，密封构件和Y形填料。 密封附接槽在其外圆周上台阶形成浅底部。 密封构件在其外周侧包括与浅底部匹配的切口部。 Y形密封件设置在密封件安装槽的深槽周壁和密封构件的切口部之间，背压室限定在密封构件的背面侧。 通过这种布置，密封构件的滑动表面可以大于密封构件的背压侧的有效面积。 由此，可以减小作用在滑动面上的载荷Ff与作用在反面上的载荷Fb之间的差。

    摘要： The present invention provides a scroll type fluid machine which enables both of a fixed scroll and an orbiting scroll to be cooled by means of a cooling fan, and which enables an overall size of the machine to be compact. Cooling fans 38A and 38B are connected to a rotary shaft 18 between an electric motor 15 and orbiting scrolls 26A and 26B. Outer cases 3A and 3B are provided with flow inlet openings 42A and 42B, flow outlet openings 43A and 43B, scroll ducts 44A and 44B and cooling device ducts 46A and 46B. Compression portions 6A and 6B are operated by rotatably driving the rotary shaft 18 using the electric motor 15. In this instance, the cooling fans 38A and 38B are rotated with the rotary shaft. Therefore, with a simple structure having no electric fans, the fixed scrolls 7A and 7B, the orbiting scrolls 26A and 26B and the cooling device 47 can be efficiently cooled, and a compressor having a compact size and a high cooling performance can be formed.

    摘要： Durability of a seal member is improved by reducing a surface pressure thereon. A seal mechanism 24 is provided between a backpressure plate 16 and a holder 17 so as to surround an orbiting backpressure chamber 18. The seal member 24 comprises a seal attachment groove 25, a seal member 26 and a Y-shaped packing 27. The seal attachment groove 25 is stepped on its outer circumference side to define a shallow bottom portion 25B. The seal member 26 includes, on its outer circumference side, a cutout portion 26D matching the shallow bottom portion 25B. The Y-shaped packing 27 is disposed between a deep groove peripheral wall 25C of the seal attachment groove 25 and the cutout portion 26D of the seal member 26, and a backpressure chamber 28 is defined on a reverse surface 26B side of the seal member 26. By this arrangement, a slide surface 26A of the seal member 26 can be larger than an effective area of the backpressure side of the seal member 26. Thereby it is possible to reduce a difference between a load Ff acting on the slide surface 26A and a load Fb acting on the reverse surface 26B.

    摘要： Inner peripheral projections are provided on the inner peripheral surface of a wrap portion of an orbiting scroll member, and outer peripheral projections are provided on the outer peripheral surface of the wrap portion. The inner and outer peripheral projections each have an approximately triangular transverse sectional configuration defined by a narrow top of the projection and a pair of concavely arcuate surfaces extending with a wide overall width so that the projections can prevent stress concentration with the concavely arcuate surfaces to increase the mechanical strength and can be readily machined by using a tool, e.g. an end mill. When contacting the mating wrap portion, the narrow tops of the projections are readily crushed or worn. Therefore, the tops of the projections can become fit to the wrap portion without strongly contacting it many times.

    摘要： A scroll fluid machine is capable of readily providing a back-pressure chamber having an increased pressure-receiving area and yet capable of being reduced in size. A fixed scroll member is secured to a casing. An orbiting scroll member is provided at a position facing the fixed scroll member. A holder is provided at the back of the orbiting scroll member, and a coupling member is provided to face the orbiting scroll member across the holder. The coupling member couples together the orbiting scroll member and a driving shaft and performs an orbiting motion together with the orbiting scroll member. A back-pressure plate is provided at the back of the orbiting scroll member, and a back-pressure chamber is formed between the back-pressure plate and the holder.

    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.
