    • A servo accelerometer has a pair of housings having a tubular part, one end opened and the other end closed with a closing part. A frame that supports a pendulum is held between the housings. A permanent magnet is attached to each of the closing parts with a bottom pole piece interposed therebetween. Coils arranged in annular magnetic gaps are attached to the pendulum. The closing part has a recess, and the bottom pole piece is disposed in the recess. The outer circumference of the bottom pole piece faces the inner circumference of the recess with a predetermined gap interposed therebetween.

    • A scroll compressor comprises a generally cylindrical casing and stationary and orbiting scrolls both accommodated in the casing. The stationary and orbiting scrolls engage with each other to define a plurality of compression chambers therebetween. The orbiting scroll is driven by a drive shaft which is in turn supported by a frame having a thrust bearing formed thereon. One of an orbiting end plate of the orbiting scroll and the thrust bearing has an annular groove defined therein in which an annular seal member is received. The orbiting scroll is disposed between the stationary scroll and the frame with an axial gap defined therebetween. First, second, and third back chambers are formed on the opposite side of the compression chambers with respect to the orbiting end plate. The first and second back chambers are partitioned by the annular seal member. The second back chamber is provided radially outwardly of the first back chamber and between the orbiting end plate and the thrust bearing, while the third back chamber is provided radially outwardly of the second back chamber. Oil passages are provided to introduce lubricating oil accommodated in the casing into the first chamber in which a discharge pressure acts. The oil passages act to supply part of the lubricating oil to the second chamber and then to the third chamber while reducing the pressure of the lubricating oil until the lubricating oil is eventually introduced into the suction chamber.
    • 涡旋式压缩机包括大致圆柱形的壳体和两个容纳在壳体中的固定和绕动涡旋件。 固定和绕动涡旋件彼此接合以在它们之间限定多个压缩室。 绕动涡盘由驱动轴驱动,驱动轴又由其上形成有止推轴承的框架支撑。 绕动涡旋件的旋转端板和止推轴承之一具有限定在其中的环形槽,其中容纳环形密封构件。 绕动涡盘设置在固定涡旋件和框架之间,其间限定有轴向间隙。 第一,第二和第三后室相对于旋转端板形成在压缩室的相对侧上。 第一和第二后室由环形密封构件隔开。 所述第二后室在所述第一后室的径向外侧设置在所述绕动端板与所述止推轴承之间,而所述第三后室在所述第二后室的径向外侧设置。 提供油通道以将容纳在壳体中的润滑油引入排放压力作用的第一室中。 油通道用于将润滑油的一部分供应到第二室,然后到达第三室,同时降低润滑油的压力,直到润滑油最终被引入吸入室。

    • In a servo accelerometer, a support rod is formed integrally with a pole piece bottom, which is disposed between a magnetic yoke and a magnet. The support rod is extended to penetrate to the outside through a through-hole formed in a closure plate portion of the magnetic yokes. The sensing mechanism is connected via the support rod to a housing by fixing the support rod at the extended end thereof to the housing. The support rod may be formed integrally with the closure plate portion of the magnetic yoke, rather than the pole piece bottom.
