摘要： A valve (41) comprises an inlet (43), a first outlet (49) and a second outlet (55). A first valve member (57) of the valve (41) cooperates with a valve seat (59) of the first outlet (49), and a second valve member (61) of the valve (41) cooperates with a valve seat (63) of the second outlet (55). The first and second valve members (57, 61) are provided on a common driving shaft (67) which is displaceable by an electric actuator (69) to regulate an air flow through the first outlet (49) and an air flow through the second outlet (55). The first and second valve members (57, 61) are combined into a single integrated valve member (65) which cooperates with both the valve seat (59) of the first outlet (49) and the valve seat (63) of the second outlet (55). A simple and compact structure of the valve (41) is obtained in this manner. The valve (41) is used in an air-assisted fuel-injection system (3) of an internal-combustion engine (1), wherein the first outlet (49) of the valve (41) is connected to a bypass (51) of a throttle valve (29) of the engine (1) and the second outlet (55) of the valve (41) is connected to an air-assisted fuel injector (31) of the fuel-injection system (3). In this manner, both the atomization of the fuel injected by the fuel injector (31) and the idling speed of the engine (1) are controlled by a single valve (41).

摘要： In one embodiment, a constant-flow valve assembly is provided that comprises a first fluid passageway carrying fluid at a first fluid pressure, a piston chamber, and a second fluid passageway connected to the chamber and carrying fluid at the second fluid pressure. A third fluid passageway is configured to carry fluid at a third fluid pressure. An adjustable valve member is provided between the chamber and the third passageway to provide constant fluid flow to the third passageway. An adjustable restrictor assembly is positioned between the first and second fluid passageways. An inlet portion of the restrictor assembly receives fluid at the first fluid pressure and directs the fluid to a restrictor. An outlet portion receives fluid from the restrictor and directs the fluid to the second fluid passageway at the second fluid pressure. The restrictor is movable to adjust the position of entry and exit portions relative to the inlet and outlet portions to adjust a fluid flow rate through fluid pathway to the second fluid passageway, thereby adjusting the flow rate through the valve assembly.

摘要： A pressure reducer has a housing comprising an inlet and an outlet in which a flow-around body is arranged in a flow channel connecting inlet and outlet. A flow restrictor is adjustably mounted relative to the flow-around body for varying a flow rate and is movably connected with an adjusting means comprising a recirculating ball nut substantially fixed in an axial direction and rotatably mounted in the flow-around body and a rotating spindle is axially adjustable mounted in said recirculating ball nut wherein the rotating spindle is movably connected with said flow restrictor. To improve such a pressure reducer that a corresponding flow restrictor with a facilitated construction is reliable and can exactly be adjusted in position, the recirculating ball nut is detachably fastened to a turning sleeve rotatably mounted in the flow-around body and the recirculating ball nut is connected with a driving toothed wheel in a rotation-resistant manner, which is rotatable by an electric drive for the movable connected with recirculating ball nut.

摘要： Flow enhancing restrictors (50") are located within a fluid conduit to provide pressure reduction and flow enhancement. The restrictors may be used in combination with a conventional choke valve or as a stand-alone pressure reduction means. Alternative exemplary embodiments for flow enhancers are described. Each of the flow enhancers has a generally cylindrical base (60) with at least one fluid passage (64) disposed therethrough. Each of the flow enhancers also provides a dome (64) that projects upwardly from the center of the base to assist in directing fluid flow and receiving the abrasive forces associated with the fluid.
