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.

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 inertial mass is mounted for limited, resiliently opposed movement on the diaphragm, and serves to dampen diaphragm vibration caused by pressure pulses in the fluid supply conduit.

摘要： The present invention provides an electrical switch that is adapted to compensate for dimensional variations in the alignment between a resilient switch member and a movable actuation member. To this end, the electrical switch has general utility but is primarily intended for use in automotive applications. More specifically, the improved electrical switch is incorporated into a latching mechanism for controlling an electrical circuit that is provided for indicating whether the latching mechanism is in a latched or an unlatched condition. The electrical switch has a pair of overlapping and offset terminal blades and further includes a biasing arrangement for biasing each terminal blade into a predetermined alignment relative to the other. The biasing arrangement is further operable for biasing both blades relative to the movable actuation member of the latch mechanism. The actuation member is made of an electrically insulative material and has a reference surface which, due to the preload biasing exerted on the terminal blades, is maintained in continuous engagement with at least one of the terminal blades during movement of the actuation member.

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 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： For use in applying a vacuum to a choke pull-off assembly, a temperature compensating vacuum delay valve comprising a housing a first opening adapted to be connected to manifold vacuum and a second opening adapted to be connected to a choke pull-off assembly which functions to partially open the choke when a vacuum is applied. The housing includes a valve disc, yieldingly urged against the seat. A restrictor permits restricted flow between the one side of the valve disc and the other side of the valve disc when the valve disc is in sealing and a bi-metallic disc is positioned in the housing between the first opening and the valve disc and is operable upon predetermined change of temperature to move the valve disc away from a seat and thereby permit unrestricted flow between the first opening and the second opening. The valve disc is spring loaded against the seat such that it will open and allow unrestricted flow in the reverse direction.

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 two-stage high flow purge valve for an evaporative emission system of a vehicle. The valve body contains two valves for controlling fluid flow through separate parallel flow paths in the valve body. A fast-acting, pulse width modulated solenoid valve responsive to an electrical control signal from the engine control computer precisely controls flow through a low flow path, and a vacuum-responsive valve controls flow through a high flow path in accordance with the level of manifold vacuum at the engine intake. A third valve member is provided to block flow through the high flow path when the engine is off and the manifold vacuum is zero. Means for calibrating both the solenoid valve and the vacuum-responsive valves are also provided.
