Abstract: The brushless signal transmitting device comprises a rotor; a fixed housing for rotatably supporting the rotor; at least one gear in mesh between the rotor and the fixed housing; an intermediate member disposed between the rotor and the fixed housing and rotatable in synchronism with and in the same direction as the rotor at a predetermined speed reduction ratio via the gear; a guide roller supported on the intermediate member; and a flexible wiring member connected between the rotor and the fixed housing. The wiring member is wound up around the rotor counterclockwise, for instance, and then returned via the guide roller so as to be wound up around the intermediate member clockwise. Since the intermediate member is larger in diameter but smaller in rotative speed than that of the rotor, it is possible to reduce the length of the flexible wiring member required to rotate the rotor by a predetermined number of revolutions of the rotor.

Abstract: A pressure control valve for a variable displacement swash plate type compressor includes a valve element movable under a combined force of the force of a pressure responsive member and the force of a solenoid. The valve element is engageable with a valve seat which is positionally adjustably mounted on a valve case of the pressure control valve and movable in the direction of movement of the valve element. The solenoid includes an armature to which an adjustment screw is threadedly connected. The extent of the adjustment screw which projects from the armature is adjustable so that the position of the valve element is adjustable relative to the valve seat. With this arrangement, it is possible to adjust the pressure controlling characteristics exactly.

Abstract: A method of controlling the capacity of a variable capacity wobble plate compressor from an air conditioning system wherein the compressor capacity is controlled such that the degree of communication between a suction chamber and a crankcase is controlled by a pressure control valve to vary the crankcase pressure and hence the angularity of the wobble plate. The value of at least one parameter representing thermal load is detected, the magnitude of current to be supplied to an electromagnetic actuator of the pressure control valve is determined in response to the detected parameter value, and the opening of the pressure control valve is determined in response at least to the determined magnitude of current.

Abstract: A control system for controlling a compressor for an air conditioning system of a vehicle. A variable capacity type compressor is disposed to be driven by an engine of the vehicle. The compressor is adapted to vary in capacity with a change in pressure within a crank chamber thereof. A first calculator calculates thermal load on the air conditioning system, and a second calculator calculates the rotational speed of the engine. An upper limit setter sets an upper limit value of suction pressure within the compressor in such a manner that the upper limit value is increased with an increase in the thermal load, and decreased with an increase in the rotational speed of the engine. A capacity controller is responsive to a difference between the set upper limit value of suction pressure and the sensed actual suction pressure for adjusting the pressure within the crank chamber to vary the capacity of the compressor.

Abstract: A brush for removing dust from clothes comprises an outer sheath and a flat rod that is inserted in the sheath so as to be withdrawable from it axially of the sheath. Two pieces of woven cloth are attached to the upper and lower surfaces of the sheath. Fibers protrude from each piece of woven cloth, and all of them are tilted in one direction.

Abstract: A variable capacity wobble plate compressor in which a pressure regulating valve is arranged across a communication passageway communicating between a high pressure chamber and a crankcase, wherein the crankcase pressure is controlled through selective closing and opening of said pressure regulating valve, to thereby vary the capacity of the compressor. An oil guide passage means communicates between a lower portion of the high pressure chamber and an inlet port of the pressure regulating valve. When the pressure regulating valve is open, lubricating oil which has collected in the high pressure chamber is returned to the crankcase through the oil guide passage means, the open pressure regulating valve, and part of the communication passageway.

Abstract: An air conditioning system for a vehicle has a compressor adapted to vary its capacity so as to maintain the suction pressure of refrigerant. A door is arranged upstream of the evaporator in an air passage, which can assume a variable opening to vary the refrigerating capacity of the evaporator. The opening of the door is controlled in response to the set position of temperature setting means which sets the discharge air temperature, whereby the refrigerating capacity of the evaporator can be reduced when overcooling takes place, to thereby reduce the work done by the compressor for minimizing a waste of energy.
