    摘要: Eine Vorrichtung (10, 110) zur Durchflussregelung eines Fluids weist ein fluidisch steuerbares Regelventil (12, 112), eine Steuereinrichtung (14) mit zumindest einem Pilotventil (72, 74) zur Steuerung des Regelventils (12, 112) und einer Pilotsteuereinheit (38) zur Steuerung des zumindest einen Pilotventils (72, 74), einen Wegsensor (48) und einen Drucksensor (50) auf. Das Regelventil (12, 112) weist ein Schließelement (20) und eine sich daran anschließende Stange (24) auf, die entlang ihrer Längserstreckung in einer Führung (62) verschieblich gelagert ist. Die Stange (24) ist mit einem Vorspannelement (28) gekoppelt, das über die Stange (24) auf das Schließelement (20) einwirkt. Die Stange (24) erstreckt sich zumindest abschnittsweise durch einen Pilotraum (32), der fluidisch mit dem zumindest einen Pilotventil (72, 74) koppelbar ist, um gegen eine vom Vorspannelement (28) aufgebrachte Vorspannkraft ein unter Druck stehendes Pilotfluid in den Pilotraum (32) einzuleiten oder um das Pilotfluid aus dem Pilotraum (32) abzuleiten. Der Wegsensor (48) dient zur Erfassung eines Ventilzustands des Regelventils (12, 112) und zur Bereitstellung eines Wegsignals (54). Der Drucksensor (50) dient zur Erfassung eines aktuellen Drucks im Pilotraum (32) und zur Bereitstellung eines Drucksignals (56). Die Pilotsteuereinheit (38) ist dazu ausgebildet, das Wegsignal (54) und das Drucksignal (56) auszuwerten, um das zumindest eine Pilotventil (72, 74) anzusteuern. Ein Verfahren nutzt eine solche Vorrichtung (10, 110).

    摘要: A pressure relief valve for pressure equalization between an essentially closed space and the surrounding atmosphere is disclosed. The pressure relief valve includes a valve housing with:—a wall defining a flow passage with an upwardly oriented outflow,—a valve body arranged to cooperate with a valve seat arranged in the outflow,—a stem configured for axial guidance of the valve body,—a damper arranged to dampen axial movement of the stem, wherein the damper is configured such that force curves of compression and expansion respectively diverge due to hysteresis loss or pronounced hysteresis loss.

    摘要: A valve (1), in particular a heat exchanger valve, is described comprising a housing having a first port (3), a second port (4) and a flow path between said first port (3) and said second port (4), wherein a valve seat (6) having a central axis (10), a main valve element (5) and a dynamic unit (8) are arranged in said flow path, wherein said dynamic unit (8) comprises a dynamic valve element (9) and a counter element (11).
    A maximum flow through this valve should be simply adjustable.
    To this end said counter element (11) comprises an adjustable form.

    摘要: A wastegate assembly (12) having a valve (16) to control exhaust gas flow bypassing a turbine wheel of a turbocharger. The wastegate assembly (12) has a wastegate port (14) for flow bypassing the turbine wheel. The valve (16) has an arm (20) controlling a valve head (22) relative to the port (14) for selectively blocking and unblocking the port (14) to control flow. A valve seat (26) may surround the port (14) to be operable with the valve head (22) to selectively block the port (14). A contoured side wall (30) is disposed adjacent to the port (14) and extends from the turbine housing (10) so as to be radially offset from a valve margin (25). The contoured side wall (30) may have a concave portion (40) adjacent to the valve head (22) to help effectuate desired flow at specific valve opening angles.
