  • Patent number: 9664293
    Abstract: A vacuum valve includes a valve housing with a valve opening, a closure member, a valve rod on which the closure member is mounted and which is axially adjustable for adjusting the closure member between open and closed positions, an elastic seal arranged on a front side of the closure member or on the valve seat of the housing, a sealing surface arranged on the other of these, and against which the seal abuts in the closed position, and at least one support part arranged on a rear side of the closure member remote from the valve seat. The abutment between the support surface of the support part and the valve housing is effected in an abutment plane which is inclined in relation to the displacement direction about an axis which is at right angles to both the displacement direction and the longitudinal axis. The support part is pivotable in relation to the closure member about a pivot axis, which is at right angles to both the displacement direction and the longitudinal axis of the valve opening.

  • Patent number: 9038985
    Abstract: A valve, in particular a vacuum valve, in which, in order to close a passage opening, in particular of the valve, at least one closure member can be moved by a valve drive, starting from a maximum open position, in which the closure member opens the passage opening at least partially, first on a first partial path into an intermediate position, and the closure member can be moved, starting from the intermediate position, on at least one second partial path which is angled away from the first partial path into a closed position, in which the closure member closes the passage opening, the valve drive having at least two cylinder spaces which are loadable in each case with a pressure medium, at least one piston being mounted displaceably in each of the cylinder spaces, and the pistons being supported on one another by way of at least one prestressing element.

  • Patent number: 6745753
    Abstract: A high-pressure injection system including a high-pressure pump having a plunger cylinder, the plunger cylinder having a delivery chamber and a high-pressure sealing surface on an outlet side, a port element arranged on the outlet side of the plunger cylinder and having a first end face and a second end face, the port element flow-connected to the delivery chamber and an outlet valve, the first end face of the port element facing the plunger cylinder, and a high-pressure line element arranged on an outlet side of the port element. The high-pressure line element comprises a high-pressure sealing surface. The high-pressure line element bears against the second end face of the port element. The port element is clamped between the plunger cylinder and the high-pressure line element. The first and second end faces of the port element each comprise a high-pressure sealing surface.

  • Publication number: 20020017278
    Abstract: A high-pressure injection system including a high-pressure pump having a plunger cylinder, a port element arranged on an outlet side of the plunger cylinder and having an outlet port, a first end face and a second end face, and a high-pressure line element arranged on the outlet side of the port element. The plunger cylinder has a delivery chamber. The port element is flow-connected to the delivery chamber and an outlet valve. The first end face of the port element faces the plunger cylinder. The high-pressure line element comprises a common rail with a high-pressure sealing surface. The common rail bears against the second end face of the port element. The port element is clamped between the plunger cylinder and the common rail. The first and second end faces of the port element each comprise a high-pressure sealing surface.
