  • Patent number: 8500089
    Abstract: A method of operating an on-off valve comprises closing one of two openings of a valve body with a seal member of a closure element within the valve body, the valve body being within an evacuation pipe connected between a process chamber and an evacuation apparatus; moving the closure element, using a linear driver, so that the seal member is moved away from the one of the two openings; and positioning the closure element into a retreat portion in an surface of the valve body, using the linear driver and a pivotal driver adapted to pivot the closure element between the one of the two openings and the retreat portion, so that the seal member is closed inside a protection seal member of the closure element to surround the seal member, thereby preventing the seal member from being directly exposed to the process gas.

  • Patent number: 8485498
    Abstract: A rotational moving point of a connection between a rod and a valve swings between a full open point, at which the valve is fully opened, and a full close point, at which the valve is fully closed. An apex of this swing is set at a point, which is between the full close point and a half point and satisfies a relationship of ?P>?A where ?P denotes an angle that is defined between a first imaginary line, which connects between a bearing center of a rod bearing and the full open point, and a second imaginary line, which connects between the bearing center and the apex of the swing, and ?A denotes an angle that is defined between the first imaginary line and a third imaginary line, which connects between the bearing center and the full close point.

  • Patent number: 8474482
    Abstract: A switching valve is proposed that switches between at least two different outlets with the aid of a valve closing body and a valve seat. The valve contains an actuating device that can be actuated by the user. The actuating device acts on an advancing device that advances the valve closing body from a stable, discrete position into another stable, discrete position. The advancement can be caused either by the interaction of beveled surfaces or by means of the flow of water.

  • Patent number: 8474789
    Abstract: A magnetic sensing surface of a stroke sensor is placed in an angular range between a first imaginary line and a second imaginary line. The first imaginary line is an imaginary line that coincides with a center line between first and second magnets of a magnetic movable body when a wastegate valve is placed to have a full close degree of the wastegate valve. The second imaginary line is an imaginary line that coincides with the center line between the first and second magnets when the wastegate valve is placed to have a half degree between the full close degree and a full open degree of the wastegate valve.

  • Patent number: 8448918
    Abstract: A gate valve for a vacuum chamber comprises two carriers (5a) each connected to a frame structure providing an essentially plane front by two parallel links (6) and to an actuating rod (12a) by parallel levers (14). Upward motion of the actuating rods (12a) by a piston (17) causes, via the levers (14), upward motion of the carriers (5a) which is transformed into a circular motion by the links (6) where the carriers (5a) at the same time approach the front while remaining parallel to it, moving sealing plates (9) which are fixed to the carriers (5a) to an active position where they press against the front and seal openings (3) therein. Retraction of the piston (17) effects an inverse motion, whereby the sealing plates (9) are completely removed from the openings (3) and the latter made easily accessible.

  • Patent number: 8439281
    Abstract: A modular coatings sprayer includes a valve housing in which there is defined a nozzle orifice and a valve-shaft bore opposite the nozzle orifice. A housing side wall extends between the orifice and bore and defines an internal fluid passage. The side wall includes an opening through which pressurized fluid is introduced into the fluid passage. A valve including a valve shaft with opposed back and nozzle-closing ends is sealably supported within the bore such that (i) the nozzle-closing end is situated within the housing and the back end is situated external to the housing and (ii) the valve shaft can axially reciprocated between a first position in which the nozzle-closing end does not seal the nozzle orifice and a nozzle-closing position in which the nozzle-closing end seals the nozzle orifice such that pressurized fluid within the fluid passage is prevented from exiting through the nozzle orifice.

  • Patent number: 8418990
    Abstract: Disclosed are valve actuator assemblies for high speed bottle filling machines. These actuators have a shaft that is pivotable on its longitudinal axis, a linkage fork connected to the shaft to pivot therewith, and a follower arm coupled by a magnetic coupling to the shaft. The magnetic coupling helps reduce carbon dioxide leakage. There may also be a second set of magnets which define pivoting dwell positions.

  • Patent number: 8413573
    Abstract: Helical spline actuators can be employed to actuate ball valves. In certain embodiments, an actuator can include a remote operated vehicle shaft, an internally splined shaft, and an externally splined shaft that can be used in combination to actuate a ball valve. In certain embodiments, an actuator can include a piston that is displaced axially and not rotated, an externally splined shaft, and an internally splined shaft that can be used in combination to actuate a ball valve. In certain embodiments, an actuator can include a piston, a spring, a spring cap, and a joint member wherein the spring cap and joint member translate axial force from the spring to the piston. In certain embodiments, an actuator can include a bearing that insulates a piston from rotational forces exerted by an externally splined shaft.

The flush actuator assembly includes a valve actuator having a first end, a second end, and an aperture extending therebetween. The aperture is adapted to surround at least a portion of the relief valve post. Movement of the valve actuator in a first direction engages the relief valve post at a first location on the post and displaces the relief valve post by a first separation distance. Movement of the valve actuator in a second direction engages the relief valve post at a second location on the post and displaces the relief valve post by a second separation distance. The first separation distance and the second separation distance are different.
