  • Patent number: 10113477
    Abstract: A turbocharger (10) has an improved wastegate valve assembly (32) wherein a valve member (35) moves freely within a lever arm (34A), and therefore, is displaceable sidewardly across the opening (28) of the wastegate port (28). The valve member (35) and associated seat (36) respectively have male and female forms so as to sealingly engage with each other when the valve body (35) is in the closed position. As such, the valve member (35) can move freely as it engages the seat (36) to provide a tight uniform seal therebetween. Additionally, the seat (36) may be formed as an insert which fits within the wastegate port (28) and is also free floating in the direction extending across the port (28) which further assists in self-centering of the valve member (35) and seat (36).

    Abstract: In a face sealing annular valve, an annular valve member is retained around or within a guide. The annular valve member is configured so that, when the annular valve member and the annular valve seat are coaxial, the spacing between the guide means and the guide-engaging surface region increases with distance along the central axis from a minimum of spacing between the annular valve member and the guide means. An end stop limits the tilt of the annular valve member. Advantageously, the annular valve member has restricted radial movement, enabling a good seal to be formed, while being unable to simultaneously contact diametrically opposite sides of the guide and jam.

  • Patent number: 6431207
    Abstract: A high-pressure fluid control valve is disclosed for operating a fluid-actuated device. Preferably a ball-poppet and frusto-conical valve seat adapted for substantially line-type contact therebetween are provided with an upstream restricted flow area in order to substantially minimize sonic flow damage to the actual sealing surface of the valve seat. Preferably, the ball-poppet is movable within a poppet guide that is allowed to float radially in order to allow the ball-poppet to be substantially self-centering with respect to the valve seat. In addition, cross-over leakage is preferably negated by closing an exhaust ball-poppet just prior to opening a supply ball-poppet.

  • Patent number: 6431209
    Abstract: A high-pressure primary fluid control valve and a multi-pressure selector fluid control valve are disclosed for operating a fluid-actuated device. Preferably a spherical ball-poppet and frusto-conical valve seat adapted for substantially line-contact therebetween are provided with an upstream flow area adjacent the line-contact in order to substantially minimize sonic flow damage to the actual sealing surface of the valve seat by shifting it away from such line-contact seating. Preferably, the ball-poppet is movable within a poppet guide that is allowed to float radially in order to allow the ball-poppet to be substantially self-centering with respect to the valve seat. In addition, cross-over leakage is preferably negated by closing an exhaust ball-poppet just prior to opening a supply ball-poppet. These principles and features are equally applicable to either or both of the primary or the multi-pressure selector fluid control valves.

  • Patent number: 6308930
    Abstract: The invention relates to a regulating valve having a valve housing (1) and an essentially horizontally arranged linearly movable valve member (2) for regulating a flow through the valve. The valve member is by a cylindrical portion (22) arranged in a bearing (6) contained in the valve housing. To reduce the wear to which the bearing paths of the valve member and the bearing are subjected and, resulting therefrom, the deterioration of the guiding of the valve member, the outer bearing path of the bearing is arranged with a “bed” in the base of the bearing path. The “bed” comprises a depression (29) which is formed as a part, limited by generatrices, of a cylindrical surface having a cross-sectional radius (30) which corresponds to that of the cylindrical portion or just above and is smaller than half of a vertical diametrical dimension of this outer bearing path, and a centre angle (31) of preferably about 70°.

  • Patent number: 6270054
    Abstract: A universal coupler for a self aligning linear actuator for a valve assembly. The self aligning linear actuator utilizes a drive screw or other threaded drive means to drive a plunger for a throttle valve. The drive screw rotates within a frame while a threaded collar or ball screw coupled to a drive coupler drives the plunger parallel to the drive screw. The universal coupler relieves any bending strain induced by misalignment between the drive screw and the plunger by allowing pivotal movement of the drive coupler relative to the drive screw.

  • Patent number: 6230742
    Abstract: A two-headed force-balanced poppet valve assembly wherein the spacing of the valve heads along the pintle shaft is directed by the spacing between the valve seats during assembly and wherein at least one of the valve heads is compliantly mounted on the pintle shaft. The valve body has a central chamber separating first and second valves disposed at opposite ends of the chamber for ingress an/or egress of gas or liquid, one of the valves opening into the chamber and the other valve opening out of the chamber. Axial motion of the pintle shaft causes the valves to be opened or closed simultaneously. One of the valve heads is fixed to the pintle shaft and the other valve head is axially slidable on the shaft and is retained thereon by swaging of the shaft. A compression spring is compressedly retained on the shaft inboard of the slidable head to continuously urge the head against the swage, thereby preventing the head from sliding inwardly along the shaft during valve actuation.

  • Patent number: 6213447
    Abstract: A poppet valve wherein centering of the valve stem and head and mating of the valve head to the valve seat are compliantly directed by contact with the valve seat. The poppet valve employs an integral radially-floating valve stem sealing guide or bearing in the valve body, permitting lateral compliant movement of the valve stem as required. The guide also is configured to form a face seal against the valve body, thus permitting the face seal and a valve actuator solenoid to be biased by separate, independent springs, each of which may be optimized for its particular function. Further, the valve head is tiltably and sealably disposed upon the valve stem to permit the valve head to be guided and oriented into the valve seat by contact with the seat itself.

  • Patent number: 6095490
    Abstract: A flow control valve having a seating surface formed on a valve element to contact a valve seat when the valve is closed has a shape of a part of a hypothetical spherical surface having a spherical center at a center of a supporting member. Therefore, the distance from the center of the supporting member to the seating surface is kept constant, and the valve element can be seated at a periphery of the valve seat without a gap, even if the shaft is inclined. Thus, the valve leakage is reduced. The supporting member supports a shaft connected to the valve element movable in an axial direction of the shaft. The center of the supporting member is aligned with a center of the valve seat. Movement of the supporting member in a radial direction of the supporting member is prohibited. Therefore, the center of the supporting member is not displaced from the center of the valve seat in the radial direction. Accordingly, the displacement of the shaft in the radial direction can be prevented.
