摘要： Check valve units having one or more sound attenuating members are disclosed. A check valve unit includes a housing defining an inlet port, an outlet port, and a chamber in fluid communication therewith thereby defining a flow path from the inlet port through the chamber to the outlet port. The chamber includes first and second valve seats and has a sealing member disposed therein that is moveable from a position seated on the first valve seat to a position seated on the second valve seat. A sound attenuating member is disposed in the flow path downstream of the chamber, within the chamber, or both. In another embodiment, the check valve unit includes a Venturi portion in fluid communication with the chamber. The Venturi portion has a fluid junction with the flow path downstream of the chamber or forms the discharge section of the Venturi portion thereby defining the outlet port.

摘要： An engine system having a flowpath between a junction upstream of a turbocharger and an intake manifold that includes an ejector and an aspirator connected in parallel relative to one another within the flowpath is disclosed. The motive flow through the ejector is in the opposite direction relative to the direction of the motive flow through the aspirator, and both the ejector and the aspirator have a suction port fluidly coupled to a device requiring vacuum. The engine system also includes a first check valve disposed in control of the motive flow through the ejector and a second check valve disposed in control of the motive flow through the aspirator and may also include a control valve in fluid communication within the flowpath upstream or downstream of the ejector and the aspirator that controls the flow into and/or out of both thereof.

摘要： Venturi devices that create vacuum have a housing defining a motive passageway converging toward a suction chamber, a discharge passageway diverging away from the suction chamber, and a suction passageway in fluid communication with the suction chamber. Within the suction chamber, a motive exit of the motive passageway is generally aligned with and spaced apart from a discharge entrance of the discharge passageway to define a Venturi gap, and the suction passageway enters the suction chamber at a position that generates about a 180 degree change in the direction of suction flow from the suction passageway to the discharge passageway. The motive passageway may terminate in a spout protruding into the suction chamber disposed spaced apart from all one or more sidewalls of the suction chamber and may subdivide downstream of the single entrance into two or more subpassageways each leading to one of two or more motive exits.

摘要： A variable flow valve assembly is disclosed, and includes a main body, a piston, a position sensor, a controller, a solenoid, and a cover. The main body defines a chamber, an inlet port, an outlet port, and a wall located between the inlet port and the outlet port. The wall defines a metering orifice for selectively allowing a medium to flow from the inlet port to the outlet port. The chamber of the main body includes a pressurized chamber. The piston is moveable within the chamber of the main body in a plurality of partially open positions to vary the amount of medium flowing through the modulation orifice. The piston separates the pressurized chamber from the inlet port. The position sensor determines the position of the piston within the chamber of the main body, and the controller is in signal communication with the position sensor.

摘要： A latching solenoid gate valve is disclosed, and includes a housing defining a conduit having a flow path therethrough and a cavity separating the conduit into a first section and a second section. The latching solenoid assembly also includes a gate assembly enclosed within the cavity of the housing and a first solenoid assembly and a second solenoid assembly seated within the cavity with the gate assembly linearly translatable therebetween. The gate assembly includes a first gate member comprising magnetizable material and defining an opening therethrough. The first gate member is linearly movable within the cavity between an open position with the opening aligned with the conduit and a closed position with the opening out of alignment with the conduit. The first gate member is moved linearly from either the open position or the closed position.

摘要： A sprung gate for a valve having an endless elastic band sandwiched between first and second gate members that each define an opening therethrough in an open position portion thereof, which collectively form a passage through the sprung gate. The first gate member includes a fastener connected to a fastener receiving member of the second gate member thereby securing the first and second gate members together as a unit. This sprung gate unit is operatively connected to an actuator for linear translation within a pocket of a conduit to control fluid flow through the conduit. This assembled device may be manufactured using spin welding to sealingly mate the conduit to a housing enclosing the actuator.
