Abstract: A positive displacement rotary mechanism has three identical rotary helical intermeshing lobes that cooperate with a stationary cylindrical member extending centrally thereof to define a repetitive working space internal of the lobes having boundaries along and between the lobes and along and between the lobes and the cylindrical member which boundaries move on rotation of the lobes to effect expansion and contraction of the working space while repetitively moving same from one of the ends of the lobes toward their other end.

Abstract: A disk on a wheel-tpe odometer assembly is provided with a integral spring pawl that operates with the normally provided transfer teeth on the highest number wheel to effect a positive detent that prevents this last wheel from backward droop.

Abstract: A hydraulic mount assembly is disclosed having expandable primary and secondary fluid chambers, an orifice track for damping action and a damping decoupler. During low level dynamic loading of the mount, hydraulic pressure activates the decoupler. At higher level loading, fluid passes through the orifice track between the two chambers providing the damping action. An expandable pneumatic bladder is mounted within the primary chamber. A control system including two one-way valves governs ingress and egress of outside air to the pneumatic bladder, thereby selectively reducing the overall damping and dynamic rate characteristics in response to sensed vehicle operating conditions. This reduction is accomplished by allowing the bladder to inflate with air providing a relatively soft, engine isolating mount. Alternatively, the control system allows controlled bladder deflation, selectively returning the mount to relatively hard characteristics.

Abstract: In a liquid cooling system for an internal combustion engine, an expansion tank which is of a design comparable to that of the expansion tank of a domestic heating system is provided on the engine block with a jacket so that an expansion tank located at the highest point of the cooling system becomes unnecessary. A simple filler neck with a cap having a pressure relief valve and a vacuum valve is provided on the cooler for refilling cooling liquid.

Abstract: A coupling for a fluid conduit under pressure has a plug carrying O-rings and inserted in a socket. A bead on the plug forms a stop for location of the O-rings. A nut rotatably mounted on the plug and held adjacent the bead has an elongated threaded annulus engaging threads on the socket so that nut rotation in either direction causes corresponding axial movement of the plug. Upon disconnection of the coupling the nut is partially backed off to remove the plug causing pressure release while the nut is still attached to the socket.

Abstract: A hydraulic mount is construded as a pair of mounting members, an elastomeric body that connects these members, an elastomeric diaphragm that is connected to one of the members and cooperates with the elastomeric body to define a closed cavity, and a partition that divides the cavity into a chamber enclosed by one side of the partition and the elastomeric body and another chamber enclosed by the other side of the partition and the diaphragm. A cylindrical sleeve interconnects the elastomeric body and one of the mounting members and sealingly peripherally clamps the diaphragm to the one mounting member independent of the partition which is mounted for unrestrained reciprocal movement and solely separates the chambers. A liquid fills the chambers and a damping orifice connects the chambers to provide damping. The damping orifice is provided by forming the partition with a spiral groove in an annular surface thereof that cooperates with an interior wall on the one mounting member to define the damping orifice.

Abstract: A variable stroke axial piston machine having a balance disk that conjointly tilts and is driven with a swash plate to balance a rotating couple induced by the pistons.

Abstract: A condenser for an air conditioning system has a tube and fin design. The tubular flow path divides into two parallel paths at the condenser inlet. The two paths combine at a junction at a point about two thirds of the distance to the outlet. A single path connects the junction to the outlet. In general condensation of the refrigerant occurs in the dual path and liquid flows at high velocity in the single path to the outlet for better heat transfer and reduced liquid volume in the tubular path.

Abstract: A motor vehicle engine mount has two inner bodies which are directed toward each other and form a gap therebetween. Each of these bodies is connected to the interior of a frame via rubber webs and a connecting piece rigidly attached to one of the inner bodies is held in a sliding manner on the other inner body via a slot and a locking screw in the position which becomes established in the loaded resting state.

Abstract: A motor vehicle air conditioning and heating system having an evaporator and a valve controlled heater core is provided with a cold air bypass around the heater core and upper and lower compartment outlets which outlets and bypass are controlled by a single mode valve to provide a bi-level mode. In one embodiment, the mode valve comprises a singular valve element. In another embodiment, the mode valve comprises two valve elements which are linked together.

Abstract: A dynamic absorber for a motor vehicle comprises the engine, radiator, air conditioning condenser and electric radiator fan all supported on a module support to form a module. The module is mounted on the vehicle body with elastic mounts with the center of gravity of the module located approximately at the anti-node of the vehicle body. Both the module and the idle speed of the engine are tuned to the first major beaming mode of the vehicle body.

Abstract: A variable stroke axial piston machine having a balance disk that conjointly tilts and is driven with a swash plate to balance a rotating couple induced by the pistons.

Abstract: A deflatable sealing member forms a weatherstrip to seal a closure opening. The sealing member includes an operative tubular section designed to provide tight interference engagement between the closure and vehicle body when vented to atmosphere and expanded by built-in resilient memory. A bellows pump is connected to the sealing member through a flow control circuit. The bellows pump serves to deflate the sealing member during closing of the closure. The bellows pump is adapted for convenient mounting in a cavity in the closure or vehicle body spaced from the closure hinge area. A flexible cable connects the bellows pump to the closure or vehicle body to provide the necessary actuation for operation of the bellows pump in response to the swinging movement of the closure. As the closure closes and latches, a valve is opened to vent the sealing member to ambient pressure, and the sealing member expands by resilient memory to its full cross section so as to provide a tight seal.

Abstract: A tube coupling having a ring seal with a U-shaped cross section that is encapsulated in a socket member when engaged and compressed by the free plug end of a tube and sealingly contacts the end of the tube at the radial end surface and inner and outer diameter wall surfaces thereof and also three surrounding surfaces of the socket member.

Abstract: A two-stage elastomeric refrigerant seal has a seal body with a primary seal section adapted for low compression and a secondary seal section adapted for high compression. The seal body is secured to a retainer in an arrangement such that the secondary seal provides pressure assisted sealing on the seal body from the sealed gas acting on the primary seal and in addition provides physical shielding of the primary seal from the refrigerant and any contaminants therein.

Abstract: A catalytic converter has a monolith with a plurality of catalyst coated passages to which internal combustion engine exhaust gases are directed with a nonuniform velocity profile that is highest at the center. A flow distributor is mounted in the converter downstream of the monolith that restricts flow centrally through the monolith while allowing relatively free flow radially outward toward the periphery to thereby alter the velocity profile at the entrance to the monolith so as to effect substantially equal distribution of the gases between all the monolith passages without extracting heat from the gases prior to entering same and without adding substantial back pressure.

Abstract: An articulated air valve arrangement in an air outlet of a motor vehicle heating, air conditioning and ventilation system has two vanes mounted for pivotal movement at right angles relative to each other. A single operator is slidably mounted on and pivotal with one of the vanes and is operatively unidirectionally linked to the other vane so as to effect pivotal movement of the one vane independent of the other vane on pivotal movement of the operator and, alternatively, the operator effects pivotal movement of the other vane independent of the one vane on sliding movement of the operator.

Abstract: A hydraulic mount assembly includes a pair of mounting members connected to each other through a hollow elastomeric body. The body is closed by a resilient diaphragm so as to form a cavity for damping liquid. A partition or plate is provided to divide the fluid filled cavity into two distinct chambers. A primary chamber is formed between the partition and the interior wall of the body. A secondary chamber is formed between the partition and the interior wall of the diaphragm. The partition includes at least two flow passages connecting the two chambers. A sliding gate extends across the opening to one of the passages. This gate is displaceable to direct an infinitely variable flow of liquid between the primary and secondary chambers to provide an infinitely variable damping effect. The gate is actuated by a linear solenoid providing this desired proportional operation. The other passage opening remains fully open at all times. In another embodiment, a rotary valve extends across the passage entry.
