摘要:
A friction clutch such as an electromagnetic clutch, in which a driving friction surface is formed on a rotor integral with a rotationally driven pulley and a driven friction surface in opposed relation to the driving friction surface is formed on an intermediate member pivotally mounted on a boss by a pin, is disclosed. When the rotor is in rotation, the armature portion of the intermediate member is attracted by an initial energizing means for generating a comparatively small force such as an electromagnetic coil so that the intermediate member is rotated around the pin. When the friction surface of the intermediate member is lightly pressed against the friction surface of the rotor, the friction force exerted tangentially to the contact surface causes the intermediate member to rotate further around the pin and generate a large force along the normal. Thus, the friction force is increased thereby making it possible to transmit a large power from the rotor to the boss through the intermediate member.

In a hybrid type compressor, a one-way clutch is provided between a magnet rotor and a rotor shaft for allowing rotational driving force generated by an electric motor unit to be transmitted only from a rotor to a shaft. Thus, the rotational driving force generated by a vehicle engine is not transmitted from the rotor shaft to the magnet rotor. That is, an inertia moment of a rotational system with respect to a vehicle engine is made small, thereby reducing the impact vibration when the clutch mechanism engages.

A power transmission apparatus which can function as a torque limiter during an overload condition. A Belleville spring is provided for generating mutual frictional engagement in areas between a flange part integral to an inner holder member, a washer, arc shaped projections of a flange part of a hub and a washer. As a result, during a normal condition of a compressor, the rotating movement of the inner holder member located adjacent to the rotating movement source is transmitted via the frictional engagement mechanism to a hub and then to a rotating shaft. Contrary to this, during an overloaded condition, a slippage is generated in the area between the washer and the arc shaped projections of the flange part of the hub as a frictional engaging area of a lower coefficient of friction. This slippage causes the washer to sink into the recess of the hub, which causes the washer to be displaced in the direction of the axis of the rotating shaft, which causes the pressing force to be reduced in the Belleville spring, resulting in a free rotating movement of the flange part.

A metal halide discharge lamp with which essentially permits disusing mercury is provided. The metal halide discharge lamp comprises a refractory and transparent hermetic vessel, a pair of electrodes fixed to the hermetic vessel, and a discharge medium sealed in the hermetic vessel and containing a first halide, a second halide, and a rare gas. The first halide is a halide of metal which achieves a desired light emission. The second halide has a relatively high vapor pressure, being at least one halide of metal which is unlikely to emit a visible light compared with the metal of the first halide and acts as a buffer gas.

摘要:
A variable capacity compressor like a swash plate type where a pressurized fluid is fed to a control pressure chamber such as a swash plate chamber to apply a backpressure to a piston etc. and the backpressure is changed by the capacity control valve, wherein the valve is streamlined and reduced in cost by providing a simple valve such as a two-way solenoid valve as a capacity control valve in a feed path to or discharge path from the control pressure chamber. By controlling the duty ratio of the valve, it is possible to smoothly change the capacity of the compressor. Further, a torque sensor is provided at a drive shaft, and the valve is controlled by a control unit to change the discharge capacity of the compressor in accordance with that detection value.
