摘要： A two-position gate valve has a gate defining a full-flow passageway therethrough and defining a restricted-flow passageway therethrough, without defining a closed position. The full-flow passageway has an entrance with a first area and an exit with a second area, the second area being smaller than the first area, and the full-flow passageway continuously tapers from the entrance to the exit thereof. The restricted-flow passageway has an entrance with a third area and has an exit with a fourth area, the fourth area being smaller than the first area, the second area, and the third area, and the restricted-flow passageway continuously tapers from the entrance to the exit thereof. Flow through the full-flow passageway is in a first direction and flow through the restricted-flow passageway is also in the first direction and the ratio of the fourth area to the second area is in a range of 5 to 15.

摘要： Check valves, Venturi devices and engines having such check valves, define an internal cavity having a first port and a second port, a first seat and a second seat, and a translatable seal disk. The check valves have an outlet conduit extending from the second port and/or the first seat has a first annular seal bead and a second annular seal bead disposed radially inward of the first annular seal bead with a plurality of ribs extending between the first annular seal bead and the second annular seal bead within the fluid flow path of the first port. The outlet conduit defines an outlet passageway having a restrictor profile that is circular in a transverse profile, and the ribs decrease the flow area of the fluid flow path of the first port by about 10% to about 60%.

摘要： Magnetic latching valves have a housing with first and second ports in controlled fluid communication with one another. Enclosed within the housing is a linearly translatable armature within a solenoid. The armature is movable between open and closed positions and is connected to a poppet valve. A permanent magnet is fixedly seated at a position for magnetically latching the armature in the open position, and a spring is seated with a first end against the poppet valve and a second end against the housing. The spring biases the poppet valve closed when the armature is in the closed position and has a pre-selected spring rate that mechanically relieves pressure if the spring rate is exceeded. The armature is moved to the open position after a pulse of voltage to the solenoid and is in an unpowered state thereafter. Vehicle fuel refueling system are disclosed that include a magnetic latching valve.

摘要： An internal combustion engine having an intake manifold, a compressor in fluid communication with the intake manifold, a charge air cooler in fluid communication with and between the compressor and the intake manifold, a throttle controlling fluid communication between the air charge cooler and the intake manifold, and a condensate collection reservoir that collects condensate from the air charge cooler and is in fluid communication with a suction port of a Venturi device in a bypass loop around the throttle. A motive inlet of the Venturi device is in fluid communication upstream of the throttle and a discharge outlet is in fluid communication downstream of the throttle, and under operating conditions that provide an adequate pressure drop across the Venturi device, the suction port draws condensate from the condensate collection reservoir and introduces the condensate into the intake manifold as a mist.

摘要： An evacuator for supplying vacuum to a device in a boosted engine air system is disclosed. The evacuator defines a body comprising a converging motive section, a diverging discharge section, at least one suction port, and a Venturi gap located between an outlet end of the converging motive section and an inlet end of the diverging discharge section. A lineal distance is measured between the outlet end and the inlet end. The lineal distance is decreased in length if higher suction vacuum at a specific set of operating conditions is required and the lineal distances is increased in length if higher suction flow rate at the specific set of operating conditions is required.

摘要： A Venturi device has a body defining a motive section and a discharge section converging toward and spaced a distance apart to define a Venturi gap, defining a first suction port and a second suction port each in fluid communication with the Venturi gap, and defining a chamber having an outlet end of the motive section and an inlet end of the discharge section dividing the chamber into a first portion and a second portion in fluid communication with one another above and below the inlet and outlet ends and through the Venturi gap. The first and second portions both have a plurality of spaced apart fingers protruding radially and axially from an inner wall thereof. A suction housing is sealingly connected to the chamber and collectively defines a check valve with the body, and a cap is sealing connected to close another end of the chamber.
