    摘要： This system is a pneumatic actuation valve assembly that can include a frame; a timing spool housing; a timing spool carriage; a timing spool; a magnet configured to bias the timing spool in a forward position; a main spool and configured to travel toward a frame forward portion when a fluid is received into a mid-main spool pressure area wherein the main spool actuates a bolt carried by the frame and is configured to receive a projectile in an open position and chamber the projectile in a closed position; and, a bore defined in the timing spool configured to allow pressure in a rear main spool pressure area to escape through the bore releasing rearward pressure on the timing spool allowing the timing spool to travel from the rearward position to the forward position according to an attraction of the magnet.

    摘要： A valve assembly includes a valve body, a valve bonnet, coupled to the valve body, an opening extending through the valve body and the valve bonnet, along a longitudinal axis, and a valve stem. The valve assembly also includes a valve member positioned at an end of the valve stem and arranged within the opening, the valve member being movable, along the longitudinal axis, between an open position and a closed position, an actuator housing coupled to the bonnet, and an adapter assembly coupled to the actuator housing. The adapter assembly includes an adapter element, the adapter element coupled to the valve stem and a force converter coupled to the adapter element, the force converter translating an external rotating force into an axial force.

    摘要： A first electrode coolant path is configured to cool a first welding electrode by liquid coolant flowing from a supply path through the first electrode coolant path to a return path. A second electrode coolant path is configured to cool a second welding electrode by liquid coolant flowing from the supply path through the second electrode coolant path to the return path. Three or more valves are configured to stop or reduce liquid coolant flow through the first or second electrode coolant path and configured to stop or reduce liquid coolant backflow from the return path when the first or second welding electrode is at least partially detached. At least one valve is coupled in the first or second electrode coolant path. A drawback apparatus generates a suction force to draw liquid coolant away from a gap formed when the first or second welding electrode is at least partially detached.

    摘要： A valve device includes a control device adapted to control a valve without being supplied with electricity. The control device includes at least one rotatable control cam having an outer periphery with a concave and convex shape, and a driving device adapted to rotate the control cam only in a first rotational direction, out of the first rotational direction and a second rotational direction opposite from the first rotational direction, by being supplied with a pressurized medium. The valve is placed such that a switch portion comes in contact with the outer peripheral portion of the control cam, in order that the valve is opened and closed by the control cam being rotated.
