    摘要: Ein Hochdruckventil weist einen Einlasskanal (10) und zwei Auslasskanäle (12,14) auf. Ferner ist ein Stellglied (16) zum Öffnen und Schließen der Auslasskanäle (12,14) vorgesehen. Erfindungsgemäß weist das Stellglied (16) einen Verbindungskanal (34,36) auf. Durch den Verbindungskanal (34,36) kann eine Verringerung der Druckdifferenz zwischen dem Einlasskanal (10) und dem geschlossenen Auslasskanal (14) vor dem Öffnen des Auslasskanals (14) erfolgen. Hierzu wird durch Verschieben eines in dem Verbindungskanal (34,36) angeordneten Steuerelements (22) eine Kanalöffnung (34) geöffnet.

    摘要: In a four-way directional control valve (6) of simplified construction and reduced manufacturing costs first and second hollow cylindrical valve elements (20a,20b) are arranged coaxially. Adjacent to opposite ends of said valve elements (20a,20b) first and second valve seats (13,14) and first and second valve closure elements (15,17) are provided. First and second pressure-regulating chambers (41,42) are arranged between separator walls (37,38) of said valve elements (20a,20b) and first and second partition walls (35,36) associated to said first and second valve seats (13,14). A pilot valve (30) can be switched between switching positions for introducing high-pressure fluid originating from a first pipe into the first or second pressure-regulating chamber (41,42) via a common high-pressure passage (31), a high pressure introducing hole (32) and two pilot holes (33,34) respectively associated to said pressure-regulating chambers (41,42). Said control valve (6) can be switched into a state where the first pipe (A) communicates with the fourth (C) and the second pipe (B) communicates with the third pipe (D) and to another state where the first pipe (A) communicates with the third pipe (D) and the second pipe (B) communicates with the fourth pipe (C).

    摘要: A hydraulic pilot valve consisting of a pair of pressure-reducing valves, wherein a stopper which can freely adjust maximum control inputs of operating levers of the hydraulic pilot valve is provided to make maximum pilot pressures output from the pair of pressure-reducing valves freely adjustable. Furthermore, in the hydraulic pilot valve, a stopper member for regulating a maximum control input of an operating lever is fixed to an operating lever, so that an operating force during a maximum operation of an operating lever is received by a member fixed to the operating lever. Furthermore, in the hydraulic pilot valve, an erroneous operation due to vibrations and the like are prevented by a damper mechanism interposed between a lever and a main body of the valve and fixed to an operating lever. Furthermore, a shuttle valve interposed between the output ports of the pressure-reducing valves can simplify the construction of the hydraulic pilot valve for taking out a maximum pilot pressure out of the pilot pressures of the output ports.

    摘要: Bei einer bekannten Vorrichtung zur Regelung der Leerlaufdrehzahl einer Brennkraftmaschine zur Steuerung einer in wenigstens zwei Strömungsleitungen der Brennkraftmaschine zuführbaren Betriebsmittelmenge kann es zu einer Leckströmung kommen, die vermieden werden soll.
    Erfindungsgemäß wird vorgeschlagen, das erste Ventilschließglied (42) und das zweite Ventilschließglied (52) relativ zueinander axial verschiebbar anzuordnen und über eine Mitnehmereinrichtung (60) derart zu koppeln, daß in Schließstellung des ersten Ventilschließgliedes (42) das zweite Ventilschließglied (52) ebenfalls geschlossen ist und das zweite Ventilschließglied (52) erst nach Erreichen einer vorgegebenen Öffnungsstellung des ersten Ventilschließgliedes (42) in Ventilöffnungsrichtung verstellbar ist. Durch die Wahl der Federanordnung und -auslegung der die Ventilschließglieder (42, 52) beaufschlagenden Federn (28, 54) lassen sich die Schließeigenschaften der Vorrichtung (10) anforderungsgemäß anpassen.
    Die Vorrichtung eignet sich insbesondere zur Regelung der Leerlaufdrehzahl einer gemischverdichtenden, fremdgezündeten Brennkraftmaschine durch Steuerung einer der Brennkraftmaschine über eine Brennstoffzumeßeinrichtung und einen Ansaugkanal zuführbaren Betriebsmittelmenge.

    摘要: A two-position, three-way subsea non-interflow valve design comprises a plug assembly. An elongated member is positioned within the valve for relative movement with respect to the plug assembly. A first seal on the plug assembly remains closed until a second seal with the elongated member circumscribes the function port. Further movement of the elongated member opens the first seal to allow flow from the supply to the function port. Two seals are presented in the flow path of the supply port to eliminate interflow to any other valve opening.
