摘要： A quick-connect fitting or coupling assembly is adapted for releasably connecting and disconnecting a pair of fluid conduits in fluid communication with one another. The assembly includes a socket on one of the fluid conduits for receiving the other fluid conduit inserted longitudinally therein into an interlocking engagement with a resilient barb or finger member on a retainer member disposed within the socket. A removal member is selectively slidably movable in the socket for deflecting the barb or finger member out of such interlocking engagement in order to remove the previously inserted fluid conduit. The assembly also preferably includes lateral support members for laterally supporting the fluid conduits relative to one another and thus strengthening the connection therebetween. The preferred embodiment includes a feature by which the fitting assembly is relatively tamper-resistant.

摘要： A rotary solenoid operated valve assembly having the rotary journalled in a ball race in one end of a tubular pole piece extending through a coil. The tubular pole piece has the end distal the ball race received in the bottom of a cup-shaped stator which has salient poles on the open rim and which define radial air gaps with poles formed on the rotor. A cam formed on the rotor moves a ball valve member in a direction transverse to the rotor axis for controlling flow over a valve seat provided in an inlet or outlet port. The rotor is balanced about its axis of rotation to prevent cam movement when the valve is subjected to vibration in a direction transverse to the rotor axis.

摘要： A variable area valve and pressure regulator for providing fuel vapor purge control in an evaporative emission control system of an automotive vehicle. A solenoid valve assembly selectively controls fluid communication between a fuel vapor source and an intake manifold by varying the area of an orifice associated with the solenoid valve assembly. A pressure regulator assembly is responsive to pressure differentials between an inlet cavity and an outlet cavity to further control the flow through the purge regulator. In operation, the purge regulator assembly is operable to generate nonlinear output flow characteristics which are independent of changes in the intake manifold vacuum, as well as the inlet pressure, and which further provides the desired nonlinear response.

摘要： A flow regulator for automotive vehicles of the type having a computer-controlled emission control system. The flow regulator has an electric vacuum regulator (EVR) valve that regulates the vacuum signal provided to a vacuum regulator valve in accordance with the current signal supplied to the EVR valve by the engine controller unit. The vacuum regulator valve includes a control chamber and a valve chamber that are separated by a movable diaphragm valve assembly. The preload on a biasing spring acting on the diaphragm valve assembly can be adjusted during calibration of the flow regulator for setting a first calibration point. An adjustable flow restrictor provided in the inlet portion of the vacuum regulator valve can be varied during calibration for setting a second calibration point. In addition, an anti-permeation filter is provided for inhibiting the venting of fuel vapors to atmosphere that have permeated through the diaphragm valve. In operation, the flow regulator is operable to generate substantially linear output flow characteristic between the two calibration points as a function of the current signal in a manner that is independent of changes in manifold vacuum.

摘要： A fuel vapor management valve or VMV having an electrically operated vent valve for controlling atmospheric bleed flow to a vacuum signal pressure chamber. The pressure in the signal pressure chamber controls the differential pressure acting on opposite sides of a diaphragm which moves a valve member for regulating fuel vapor purge flow from a canister to the engine intake manifold. Vacuum is applied to the signal pressure chamber through restrictive passages in a connector which prevent sonic flow choking. In one embodiment two orifices are spaced fluidically in series. In another embodiment fluidically parallel laminar flow passages are provided in an element comprising a porous filter preferably formed of fibrous material or sintered metal. In another embodiment, the laminar flow element is disposed fluidically in series with a flow restricting orifice.

摘要： Control systems including control circuitry and optional communications systems for operating a sliding power-operated member of an automotive vehicle. A powered sliding door in an automotive vehicle, such as a van, moves along a predetermined path of travel between a closed position and a fully open position relative to the body of the vehicle. Such a sliding door may be provided with one or more electrically-operated actuators for performing functions associated with the door, such as power opening and closing the door, power unlatching the door, power locking and unlocking the door, and power clamping and unclamping the door in a soft or low-momentum manner. The invention is directed toward improved control systems and circuitry for operating such power-sliding door systems. One such control system employs a wireless communications link between the door and body, which is preferably implemented using radio frequency communication signals containing digitally encoded control signals. Control circuitry is preferably provided in the body and the door of the vehicle for supervising and carrying out the foregoing functions in an orderly manner in response to requests generated locally at the door or remotely by the driver from the console of the vehicle. A second, simpler, control system provides electrically-actuated mechanisms for unlatching the door and operating the door lock without the use of either a wireless communication system or a retractable electrical cable interconnecting the sliding door to the vehicle body.

摘要： An improved cable spool arrangement is disclosed for use in powered vehicle door operating systems, or in other cable-actuated devices, having one or more actuating cables. In one form of the invention, a groove, or other open channel-like opening, is formed along a generally helical path on the cable spool, and preferably has a varying groove depth along at least a portion of the helical path in order to take up or pay out at least a portion of a cable at a correspondingly varying rate with respect to cable spool rotation and thus cause movement of a door or other movable member at a correspondingly varying rate with respect to cable spool rotation. A second, constant depth portion of the helical groove can also be provided for generally constant take-up or pay-out of a cable onto or from the constant-depth portion of the helical groove. Such varying radius groove arrangement can be used both in high displacement/low force cable movements and in low displacement/high force cable movements.

摘要： A solenoid operated valve is controlled upon increasing energization for greater flow by incrementing by a small fraction of the maximum current a target current level for the desired flow for a short duration followed by energization at the target level. Upon decreasing energization for lesser flow, the valve is energized at a target current decremented by a small fraction of the maximum current for a short duration. The result is a nearly negligible hysteresis.

摘要： A diaphragm type flow regulator has an electrically operated bleed valve to control fluid signal pressure in a chamber on one side of the diaphragm. A valve member mounted on the opposite side of the diaphragm is moved, in response to the difference in pressure between the signal chamber and a flow regulating chamber, with respect to a valve seat for controlling flow of a compressible fluid between an inlet and outlet in the flow regulating chamber. An auxiliary chamber communicates with the flow regulating chamber through a restricting orifice which function to dampen or attenuate diaphragm vibration caused by pressure pulses or transients which may occur in the fluid supply conduit. In one arrangement the auxiliary chamber is formed as part of the regulator housing. In other arrangements, the auxiliary chamber is formed as part of a separate fitting attached to the regulator flow regulating chamber inlet.
