    摘要： A cylinder has a shell (2) that rotates around a fixed central axis (1). A first chamber (7) arranged inside the cylinder is filled with liquid and transfers a supporting hydraulic force from the central axis (1) to the shell (2). The first chamber (7) is linked by a throttle (11) to a second chamber (20) located as well inside the cylinder, and in which is arranged a hermetically closed rubber hose (21) filled with gas, so that the second chamber (20) is at all times only partially filled with liquid. Thus the volume of liquid contained in the second chamber (20) can rapidly change when there is a change of pressure in the first chamber (7), so that when the shell (2) tends to vibrate, liquid flows back and forth through the throttle (11), converting wave energy in frictional heat by means of fluid friction.

    摘要： Undesirable noise developing from relative sliding between a belt (29) and a pulley (48) when the traction between the belt (29) and the pulley (48) is loosened to halt the belt (29) from being driven by the pulley (48) is eliminated or alleviated by roughening the inner surface (60) of the pulley (48) to a consistency some­what like that of sanded wood surface. Preferablly, the inner surface (60) is roughened in accordance with published Moldtech Standard 1055-5. The belt (29) has a circular crozss-section and is formed of polyurethane. Moreover, the roughened surface (60) on the drive pulley (48) improves the traction between the belt (29) and the drive pulley (48) when the belt (29) is tightened in order to be driven by the drive pulley (48).

    摘要： Un dispositif d'enroulement des spires découpées (9) de l'enrubanage d'une balle comprimée (8) comprend un enrouleur (4). Afin de pouvoir saisir de manière sûre les spires individuelles au moyen de l'enrouleur (4), ce dernier est associé à une tête d'accrochage (10) des spires individuelles et à deux barres de guidage (7) susceptibles d'être serrées sur la balle comprimée (8), transversalement à l'enrubanage, et entre lesquelles la tête d'accrochage (10) transversalement réglable par rapport à la surface de la balle accroche les spires individuelles.

    摘要： A scroll-type hermetic compressor is disclosed including a hermetically sealed housing (12), fixed and orbiting scroll members (48, 50), a stationary frame member (52) including a thrust surface (55) adjacent the orbiting scroll member bottom surface (51), and a crankshaft (32) drivingly coupled to the orbiting scroll member. A seal (158) extends from a fixed location on the orbiting scroll member bottom surface toward the thrust surface and slidingly seals thereagainst, whereby fixed radially inner and outer portions (154, 156) of the scroll member are defined which are exposed to discharge and suction pressures (110, 98) for axial compliance. The seal consists of an annular groove (152) on the orbiting scroll member bottom surface in which an annular seal element (158) is unattachedly retained. The groove may be supplied with pressurized oil to aid in sealing with the seal element or, alternatively, to provide a hydrostatic seal without a seal element.

    摘要翻译： 公开了一种涡旋式密封压缩机，其包括密封的壳体（12），固定和绕动涡旋件（48,50），固定框架构件（52），其包括邻近绕动涡旋构件底表面的推力表面（55） 51）和与所述绕动涡旋件驱动连接的曲轴（32）。 密封件158从旋转涡旋构件底面上的固定位置向推力面延伸，并在其上滑动地密封，由此确定涡旋构件的固定的径向内部和外部部分（154,156），其暴露于排放状态， 吸入压力（110,98）用于轴向顺应性。 所述密封件包括在所述绕动涡旋构件底表面上的环形凹槽（152），其中环形密封元件（158）未附着地保持在所述环形凹槽中。 凹槽可以被供应加压油以帮助与密封元件密封，或者替代地，提供没有密封元件的静水密封。
