Abstract: The apparatus includes a first tie rod end component having a first threaded surface and a second tie rod end component having a second threaded surface. The first and second tie rod end components are configured to rotatably couple to a center component in opposite directions. The tie rod end components each include a groove designed to assist a user in determining whether the tie rod ends are properly coupled to the center component. If the groove is visible to a user then the tie-rod end is not screwed in far enough. In contrast, it the groove is hidden that indicates that the tie rod end component and the center component are properly assembled to each other.

Abstract: A pipe coupling assembly includes two identical pipes each extending into an enlarged collar and then into a hemispherical socket each with a socket radius. A bulbous insert engages the sockets of the pipes. A clamping mechanism is disposed about the pipes and includes two blocks for holding the sockets into engagement with the insert. The insert has two necks both extending axially around the flow passage and fitting into the pipes. The insert defines a slot extending radially and circumferentially about the axis for allowing movement of two hemispheres relative to one another. Each of the hemispheres has an insert radius. The socket radii are greater than the respective insert radii for establishing a contact line between the insert and the sockets which becomes a contact band as the blocks move together.

Abstract: A compressor includes a housing and a drive shaft extending along a longitudinal axis and rotatably supported by the housing. A pocket is defined in the drive shaft and extends to a bottom portion having a diameter smaller than a diameter of the pocket. A pair of sealing lip portions disposed between the housing circumscribing the drive shaft. A pair of channels is defined in the drive shaft with one of the channels exposed between the spaced lip portions to deliver a lubricant therebetween under pressure.

Abstract: Each blow-off valve includes a valve body with a first movable wall defining a portion of the liquid fluid passage therein and a second movable wall defining a portion of the suction fluid passage therein. An actuator interconnects the movable walls for simultaneously moving the walls and opening the fluid passages in response to the electrical leakage-warning signal. In the species of FIGS. 2 and 3, the movable walls are integrally united with the valve body and include frangible sections that are fractured by an explosive squib to separate the movable walls from the body to simultaneously open the liquid and suction fluid passages. In the species of FIG. 5, the movable walls are separate valve elements disposed in a circular bore that opens the passages to the ambient surroundings. The actuator includes a spring, for biasing each of the valve elements out of its respective bore, and a holding device that weakens in response to the electrical leakage-warning signal.

Abstract: An air conditioning system for a vehicle includes an accumulator/dehydrator (A/D) disposed in the suction fluid line for accumulating refrigerant and a heat transfer jacket surrounds the A/D for exchanging heat with the A/D and the refrigerant therein. The heat transfer jacket may define a space between an inner wall of the A/D and an outer wall spaced therefrom with a heat transfer media disposed in the space for cooling by extracting heat from the refrigerant in the A/D. Alternatively, the jacket is defined by a double walled sleeve surrounding the A/D and defining the space for the heat transfer media. Yet another alternative is for the heat transfer jacket to comprise a thermoelectric device.

Abstract: An air conditioning system for a vehicle includes an evaporator for evaporating the refrigerant and including a predetermined portion in which refrigerant pools. A device for directing the flow of air to the predetermined portion to minimize the pooling of refrigerant in the predetermined portion includes a spool and a sheet wound around the spool for winding and unwinding the sheet. The opening is disposed in the sheet for allowing airflow to said predetermined portion of the evaporator.

Abstract: An air conditioning system for a vehicle includes a controller for periodically increasing the stroke and output of the pistons in a variable stroke compressor for periodically reducing the amount of refrigerant resident in the evaporator. The controller includes a timer for establishing predetermined time periods between the momentary spikes of periodic increases of stroke. Normally, the stroke is spiked only when the compressor is operating at a low load condition.

Abstract: An expansion device that is able to perform the functions of refrigerant expansion, flow control and shut-off. A cage extends from the ends of a body and supports a screen cover. An orifice tube extends through the body and a conical shaped valve seat forms an outwardly flared inlet to the orifice tube. A plunger defines a conical shaped valve end for engaging and sealing the conical valve seat to prevent refrigerant from entering the orifice tube. A rod extends from the valve end to react with a solenoid coil for moving the valve end into and out of engagement with the valve seat. A spring interacts between the plunger and the solenoid for urging the plunger into the valve seat.

Abstract: An electrosurgical device comprising an elongate probe member having proximal and distal extremities and a passage extending from the proximal extremity to an opening at the distal extremity. The elongate probe member is provided with an elongate cutout adjacent the opening so that the elongate probe member is formed with an elongate extension projecting alongside the cutout beyond the opening. A guide canula is mounted in the passage of the elongate probe member and has proximal and distal extremities and a lumen extending therethrough. A radio frequency electrode is disposed in the lumen and an insulating sleeve is coaxially disposed on the radio frequency electrode. A handle is secured to the proximal extremity of the guide canula for advancing and retracting the radio frequency electrode and the insulating sleeve with respect to the guide canula and for causing bending of the distal extremity of the guide cannula into the cutout.

Abstract: A vehicle climate control system having a separate control for first and second separate areas of the vehicle. The climate control system includes a three-fluid heat exchanger having a first path with a first inlet and first outlet, and a second path with a second inlet and second outlet.

A primary refrigerant loop is interconnected by a refrigerant line with the refrigerant line being connected to the inlet and outlet of the first path. A secondary loop is connected to the inlet and the outlet of the second path such that the coolant flows through the three-fluid heat exchanger to selectively cool or heat the second area of the vehicle by heat transfer within the three-fluid heat exchanger.
