摘要： A variable flow valve with position feedback is disclosed. The variable flow valve includes a housing having an inlet port and a discharge port and one or more control ports, and also includes a piston connected to a primary valve to open and close fluid communication between an inlet port and a discharge port of the housing. The housing and the piston intermesh to define an inner chamber and an outer chamber each in fluid communication with its own control port. A control port valve opens and closes at least one of the control ports to control access to a source of pressure change. A position sensor is part of the position feedback and communicates the position of the primary valve, relative to the discharge port, to a controller that operates the control port valve to hold the primary valve in a position where the discharge port is partially open.

摘要： Pressure piston actuators and systems for control of wastegate in a turbocharger pressure that include the pressure piston actuators are disclosed. The pressure piston actuator includes a housing defining a chamber and a pathway leading to the chamber, a piston disposed within the chamber, a rod connected to the piston by a ball-and-socket joint, and a spring disposed in the chamber to bias the piston, and hence the rod, into a retracted position. Then, when fluid is introduced into the chamber, the fluid applies pressure to the piston. Once the pressure overcomes the bias of the spring, the piston, and hence the rod, moves into an extended position. For the system, the pressure piston actuator has the connector on the end of the rod opposite the ball-and-socket joint connected to the valve portion of a wastegate of a turbocharger.

摘要： A collet quick connect fluid coupling includes a self-centering structure that is received within a channel (36) in a pilot (32). The channel and self-centering leg (28) ensures the collet (26) is approximately centered within the housing (22) as a tube (38) is moved into the housing. This prevents misalignment of the collet relative to the tube (38). In a preferred embodiment, the collet (26) has a ramp ( 30) on an inwardly facing surface that cams along a surface on the pilot (32), assisting the collet (26) in expanding when a tube (38) is moved into a housing (22).

摘要： Aspirators are disclosed herein that include a body defining a Venturi gap between an outlet end of a converging motive section and an inlet end of a diverging discharge section and have a suction port in fluid communication with the Venturi gap. The converging motive section defines a circular-shaped motive inlet and defines an elliptical- or polygonal-shaped motive outlet, and the diverging discharge section defines an elliptical- or polygonal-shaped discharge inlet. In one embodiment, the converging motive section defines an inner passageway that transitions as a hyperbolic function from the circular-shaped motive inlet to the elliptical- or polygonal-shaped motive outlet and the elliptical- or polygonal-shaped motive outlet has an area that is less than the area of the circular-shaped motive inlet.

摘要： A Venturi device for producing vacuum from fluids in an engine system has a body defining a Venturi gap separating apart an outlet end of a converging motive section and an inlet end of a diverging discharge section by a lineal distance, and a suction port in fluid communication with the Venturi gap. The converging motive section and the diverging discharge section both gradually, continuously taper toward the Venturi gap, the converging motive section defines a circular-shaped motive inlet and an elliptical- or polygonal-shaped motive outlet, the diverging discharge section defines an elliptical- or polygonal-shaped discharge inlet, and an inner passageway of the converging motive section transitions as a hyperbolic function from the motive inlet to the elliptical- or polygonal-shaped motive outlet.
