Abstract:
A gas generator for an air bag is provided which includes a housing having first and second outer shells each having a flange, a gas generation device disposed inside the housing and a gas jet portion for introducing a gas in the gas generation device into the air bag. The flanges of the first and second outer shells are fastened together by locally fastening the flange of the first outer shell and the flange of the second outer shell together with predetermined gaps therebetween. The flange portion has joint portions at which the flanges are attached to each other and contact portions formed between the joint portions at which the flanges are in mere contact with each other. The gas jet portion is formed of the contact portions. The contact portions are opened by buildup of gas pressure inside the housing after impact and the corresponding activation of gas generation device.
Abstract:
An assembly for providing socket plate torque restraint for a variable displacement wobble plate compressor is provided. Swing arms support a guide pin and allow for swinging motion to be directed to the pin. A translatable driving sleeve is attached to and rotates with the compressor drive shaft. The sleeve is formed with a cam section having a variable axial profile. An axially fixed follower cooperates with the cam section to generate the motion of the guide pin relative to the socket plate. The motion defines a motion of the socket plate which produces no inertial torques. The compensating torque restraint smooths the uneven driving action of the socket plate. The position of the cam section varies in relation to the displacement orientation of the socket plate, thus allowing precisely that socket plate motion, at all stroke positions, which produces no inertial torques.
Abstract:
A compressor assembly for pumping a recirculating refrigerant including input and output shafts rotatably supported within a housing and a pressure responsive clutch disposed therebetween for selectively translating torque from the input shaft to the output shaft to drive the compressor. An auxiliary clutch compressor is employed for generating an auxiliary refrigerant discharge pressure and a control valve is moveable between first and second positions to either route refrigerant discharge pressure away from the clutch or to bear upon the clutch so as to translate torque between the input and output shafts.
Abstract:
An integral link-and-pivot member for an endless power transmission chain comprising longitudinal spaced web portions joined to transversely oriented joint portions, each joint portion having an arcuate or curved surface, said surfaces facing one another and being adapted to engage a like surface of an interleaved member when assembled as an endless chain and a chain assembled from such members.
Abstract:
A driving interconnection between two eccentrically rotating members for rotation at the same angular velocity about their respective axes without angular phase shift. The invention is adaptable to join an outer rotatable member to an inner one and is particularly useful for coupling the interior rotor and the external cam ring in certain types of positive fluid displacing devices. In one embodiment, the coupler comprises a central body with four outwardly extending arms. Two of the arms engage tightly fitting slots in the inner rotating member. The other two arms pass through clearance slots in the inner member and engage tightly fitting slots in the outer rotating member.
Abstract:
Apparatus and methods are provided for relieving the compression pressure while starting an internal combustion engine 10. A passage 12 communicates via end openings 22 and 22a between the compression space 13 and the exhaust region 19 in the head 20 of the engine. A spring 16 presses against one side of a piston 15 in a valve 21, holding an end portion 23 away from the opening 22 until the engine speed exceeds the cranking speed. The pressure of the engine's lubricating oil 18 on the opposite side of the piston 15 then forces the end portion 23 against the opening 22, to close the passage 12 and permit the engine to continue running with full compression.
Abstract:
A scroll type fluid displacement machine (10) with a housing (12) a fluid inlet port (78) and a fluid outlet port (76) has an annular piston (88) that biases the balls (90) of the ball coupler and the orbital scroll (29) toward the fixed scroll (18) to move the axial tips (40 and 58) of the wraps (34 and 52) into sealing contact with the end plates (30 and 48) when fluid is pumped into the annular chamber (120). A control system (28) is provided to control the axial position of the orbital scroll (20). The control system (28) includes a solenoid valve (176) which directs fluid from a small trigger compressor (174) to the annular chamber (120) to axially move the orbital scroll (20) into sealing contact with the fixed scroll (18). The solenoid valve (176) also directs fluid from the exhaust chamber (42) to the annular chamber (120) to maintain the orbital scroll (20) in sealing contact with the fixed scroll (18). The solenoid valve (176) also directs fluid from the annular chamber (120) to the sump (232) to stop fluid compression by the scrolls (18 and 20).
Abstract:
A wobble plate piston pump in which means for holding the slipper shoes in close proximity with the wobble plate comprises a first retainer member in the form of an annular plate, loosely fitted on the drive shaft and formed with a plurality of through bores circumferentially arranged in the vicinity of its outer periphery and loosely receiving therethrough trunk portions of the slipper shoes swivellingly engaging the pistons, the retainer member being movable in directions substantially parallel to the wobble plate as the slipper shoes slide on or in close proximity to the wobble plate, a second retainer member having a hollow tubular portion loosely fitted through the first retainer member and unremovably fitted in a central bore formed in the wobble plate and a flanged portion holding the first retainer member on flanged portions of the slipper shoes to keep the latter in close proximity with the wobble plate.
Abstract:
A coupler for joining two eccentrically rotating members for simultaneous rotation about their respective axes at the same angular velocity without angular phase shift. The invention is particularly useful for coupling the rotor and cam ring in certain types of positive fluid displacing devices. The coupling includes a double crank member with a central portion extending along a first axis and two end portions extending from each end of the central portion along a second axis parallel to the first. The central portion is received in a bore in the inner member and the end portions are received in opposing mutually parallel slots in the outer member.
Abstract:
A compressor assembly for pumping a recirculating refrigerant including input and output shafts rotatably supported within a housing and a pressure responsive clutch disposed therebetween for selectively translating torque from the input shaft to the output shaft to drive the compressor. An auxiliary clutch compressor is employed for generating an auxiliary refrigerant discharge pressure and a control valve is moveable between first and second positions to either route refrigerant discharge pressure away from the clutch or to bear upon the clutch so as to translate torque between the input and output shafts. The auxiliary compressor includes a piston and a cylinder with the piston operatively mounted to an eccentric portion of the input shaft and driven by the input shaft for reciprocal motion within the cylinder to generate an auxiliary refrigerant discharge pressure.
