Abstract: A hydraulic mounting has a nozzle plate with a membrane separating a working chamber from an equalizing chamber and a ring channel connecting these chambers. A filler channel leads radially from the outside into this ring channel and makes it possible to fill the hydraulic mounting, without air bubbles, with hydraulic fluid. A closure member closes off the filler channel on the outside.

Abstract: A monolithic catalytic converter has a two-piece slip pin that extends through a monolithic substrate and is connected at its opposite ends to the housing so as to retain the substrate therein while freely allowing differential thermal expansion between the slip pin and the housing to accommodate thermal mismatch between these components.

Abstract: A hydraulic mount assembly includes a pair of mounting members connected to each other through a hollow elastomeric body of natural or synthetic rubber. The body is closed by a resiliant 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 hollow body. A secondary chamber is formed between the partition and the interior wall of the diaphragm. A decoupler is mounted for reciprocal movement in the partition in response to low level alternating pressures in the chambers. At certain small vibratory amplitudes and high frequencies the decoupler eliminates undesirable hydraulic damping. The partition also includes at least two passages connecting the two chambers.

Abstract: A motor vehicle passenger compartment has an air inlet at the base of the windshield and a valve controlling an air outlet so as to maintain the pressure in the compartment above ambient pressure.

Abstract: A hydraulic mount assembly is disclosed having a partition including a damping decoupler between two hydraulic chambers. One chamber is formed by an elastomeric member and the other by a resilient diaphragm. During dynamic loading of the mount, fluid passes between the two chambers of the mount by moving around an orifice track and/or by bypass around the decoupler causing expansion and contraction of the diaphragm. A magnetic coil is provided adjacent the diaphragm in alignment with the decoupler to supply a controlling magnetic field. The decoupler is made of a magnetic material and is positionally responsive to the variations in the intensity and direction of the controlling magnetic field. By actively controlling the decoupler position in this manner, the dynamic characteristics of the mount are varied. A control circuit with on-board transducers is provided to monitor vehicle operating and road response conditions and modulate the voltage to the magnetic coil for maximum damping effect.

Abstract: A positive displacement rotary mechanism has three and alternatively four 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 hydraulic-elastomeric mount is disclosed having a hydraulic damping decoupler with a flexible membrane mounted for reciprocal movement in a reciprocal partition in response to alternating pressure buildup in two orifice connected chambers separated by the partition and decoupler so as to effect cyclic volume change in the chambers by limited travel of both the partition and decoupler and flexing of the membrane without forcing liquid through the orifice and thus without hydraulic damping thereby.

Abstract: A hydraulic mount assembly includes a pair of mounting members connected to each other through a hollow elastomeric body of natural or synthetic rubber. 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 hollow body. A secondary chamber is formed between the partition and the interior wall of the diaphragm. The partition includes at least two passages connecting the two chambers. A sliding gate extends across the entry to the passages. This gate is displaceable to direct the flow of fluid between the primary and secondary chambers through a selected passage or passages in the partition. A solenoid actuator mounted on the partition includes multiple electric coils that allow the positive positioning of the gate.

Abstract: Method of fabricating and assembling metal catalytic converter catalyst substrates by sequentially laying strips of foil of predetermined widths onto a strip of sheet metal as the latter is formed into a single seam tube about the layers of foil to contain and restrain same, seam welding the tube along its length, and cross cutting the tube and contained layers of foil into predetermined lengths to form catalyst substrate units.

Abstract: A motor vehicle has an air duct on a swinging door that aligns with and is sealingly joined to an air duct on the vehicle body when the door is closed by a collapsible leaf spring biased bellows seal mounted between the door and vehicle body.

Abstract: A solenoid control valve has a main poppet to selectively open and close a port in a passage and when closed is subject to a fluid pressure differential tending to prevent valve opening. To facilitate valve opening, bypass passages through the main poppet are provided for reducing the net pressure on the main poppet and are controlled by a pilot valve. A solenoid and return spring control operation of a tubular plunger with an intregral pilot poppet. The main poppet is carried on a stem which has a telescoping lost motion connection to the plunger thus allowing the poppet to selectively engage a pilot seat on the main poppet for the closed valve state and for separating from the seat during valve opening.

Abstract: A return air barrier for a system for venitilation of the passenger compartment of a motor vehicle has a closure flap made of a flexible low-density material suspended, and resting by its own weight against an inclined grid in the housing of the return air barrier, and during air flow moves against the direction of outflow into the closed position. Above the closure flap within its range of travel thereof, there are several hook-like webs mounted in such a way that at the height at which flapping begins, the flap touches the free end of at least one web and, with increasing air velocity, buckles in the lower edge region, adheres snugly to the webs and is held in an angular form.

Abstract: A three-point torque strut connected between an engine and support resists rolling of the engine by reactive torque thereon while inducing with a portion of the reactive torque force from the engine a bending moment in the support that counteracts against the remainder of the reactive torque force transmitted by the strut from the engine tending to twist such support.

Abstract: A crankshaft and connecting rod assembly comprises a driver having a crank lobe with a shank received in a radial slot through a shaft so as to be driven thereby. The crank lobe has an inner side that operably contacts the shaft and an outer side that operably contacts a bore in a connecting rod and the shank has an end that also operably contacts the bore. The outer side of the crank lobe and the end of the shank each have a semi-circular cylindrical surface and these surfaces are located diametrically opposite each other and have a common axis eccentric and parallel to that of the shaft and a radius substantially equal to that of the bore whereby upon shaft rotation the crank lobe through sliding contact with the bore drives the connecting rod while the end of the shank slidingly follows the bore and cooperates with the crank lobe to prevent radial movement of the driver on the shaft to thereby maintain such drive.
