摘要： PURPOSE:To reduce a friction loss while improving the sealing property of the ends of vanes by slidably providing a tip seal on the end portion of each vane while increasing the pushing pressure of the tip seal by the introduction of high pressure. CONSTITUTION:A connecting port 14a which passes through from the bottom portion of a slide groove 14b into which a tip seal 12 on the end portion of a vane can be fitted to the inner face of a slider groove 10 is formed on each vane 6a, 6b. A slider 11 in which a slider shaft 13 is fitted in a hole 10b slides in the slider groove 10, and has an opening port 16 which is formed with ports 16a passing through the sliding face portions 10a thereof and a long groove 16b, to connecting/disconnectingly control the pressure to the tip seal 12 in the section from an optional suction air point to the vicinity of a suck-out port.

摘要： PURPOSE:To reduce a change of a detection level to an input with a declination and to improve the detection performance in a collision in the oblique direction by rotatably supporting a speed detector at the position that does not agree with its center of gravity. CONSTITUTION:The speed detector 1 is installed in the internal space of the base 2 and is rotatably supported by the axis 6 through the bearing 5. When a car is slowed down less than a fixed level in the direction Y-Y, the movable inertia body 11 gives energy to the coil spring 13 while it moves due to acceleration in the direction Y-Y, and comes in contact with the contacts 121, 122 to close the switch. Next when the acceleration F with a declination alpha acts on the detector 1, the housing 4 that has been held in the same direction as Y-Y by the elastic body 7 acts on the center of gravity, a moment of rotation around the axis is developed, the housing 4 turns through an angle at which it balances a resisting force of the elastic body 7. As a result, the axis 10 in the housing 4 deflects in the direction Z-Z, the inertia body 11 can easily be moved.

摘要： PURPOSE:To improve the seizure resistance by providing a groove connected with a compression chamber at one end in a surface facing a side plate of a vane. CONSTITUTION:If a shaft 2 is rotated, the volume of compression chambers 8a, 8b formed of a rotor 1, a cylinder 6, a vane 9, a side plate F, R, 3, 7, is increased and decreased repeatedly, so function of a compressor is achieved. In this case, lubrication oil 12 scraped corresponding to rotation of the vane 9 gets through a gap between a chip seal 13 and a groove 9f into a groove 9e in a vane side surface. The lubrication oil 12 is thus supplied uniformly to slide surfaces 9c, 9d between the vane 9 and the side plates F, R, 3, 7 uniformly. Lubrication to the chip seal 13 is performed simultaneously.

摘要： PURPOSE:To enable the gentle starting of a compressor by providing a means of reducing the balance time between the pressure in a compression chamber and a piston back pressure at the time of stopping the compressor. CONSTITUTION:A side housing 23 has a passage 26 for connecting a low-pressure chamber 24, a high-pressure chamber 25 and a high-pressure chamber 25 to the high-pressure side piping of a refrigerating cycle. The passage 26 consists of a passage which forms an inlet throttle 27 with a small sectional area and a passage which forms an expansion chamber 28 with an enlarged sectional area, and a check valve 29 as a balance-time reducing means is provided on the expansion chamber 28, while providing an outlet throttle 30 on the outlet side of the expansion chamber 28. The balance-time reducing means reduces the balance time between the pressure in a compression chamber 1 and the back pressure of a piston 3 at the stopping time of the compressor thereby, moving a swash plate 4 by the force of a spring 12 in a short time to be controlled to the minimum capacity.

摘要： PURPOSE:To secure proper sealing pressure for sealing members which are slidably moved on the inner circumferential surface of a cylinder while being hermetically sealed by the use of blowby gas by forming a communicating means introducing the pressure in a rotor center section to the tip end section of vanes. CONSTITUTION:A slider 19 is formed with a valve means composed of long grooves 32 and 33, and the length of the long grooves 32 and 33 is so designed that communicating holes 30 and 31 shall be opened within a rotation range between the rotation angle theta1 of vanes 15 and 16 at whose angle the suction stroke becomes initially effective and the rotation angle theta2 wherein theta2=180 deg.-theta1. This constitution allows the medium pressure in a space 12 at the center section of a rotor 3 to act on the back of top seals 25 and 26 via the communicating holes 30 and 31 during the suction stroke of the vane 15, thereby letting the pressure neither be excessively low nor excessively high against the top seals 25 and 26.
