    摘要： The present invention is directed to a system, device, apparatus, methodology, technique and kit that allow a party to more effectively purge a hydraulic system of trapped air, along with any residual oil. The configuration of the present invention, which connects to the external hydraulic system, collects the residual oil in an accumulation chamber with transparent sides. A worker can thus see the progress of the hydraulic purge and easily dispose of the oil without mess and exposure.

    摘要： A linear actuator system includes a linear actuator including an outer body, an inner body disposed within the outer body, a fluid chamber at least partially extending between the inner body and the outer body, a piston chamber extending at least partially within the inner body, a valve configured to selectively fluidly couple the fluid chamber and the piston chamber to each other, a piston assembly including a piston, a variable volume within the piston chamber that extends between the piston and the valve, and a gas collector assembly including a fluid passageway. The piston assembly is disposed within the piston chamber, wherein a movement of the piston assembly causes a gas separated from a liquid within the variable volume to flow through the fluid passageway, through the valve, and into the fluid chamber.

    摘要： An apparatus for driving a valve pin in an injection molding system, comprising: an actuator having a piston disposed within a master chamber, the piston being slidable upstream and downstream within the master chamber having a seal that forms a seal surface with a complementary interior surface of the master chamber, the seal surface forming opposing upstream and downstream fluid drive chambers, a bleed port extending through the interior surface of the master chamber at a position on the interior surface of the master chamber where the bleed port is: either disposed immediately downstream of the complementary interior surface of the master chamber that forms a seal with the seal surface of the piston and communicates with a downstream fluid drive chamber when the piston is in a fully upstream position, or is disposed immediately upstream of the complementary interior surface of the master chamber that forms a seal with the circumferential seal surface of the piston and communicates with an upstream fluid drive chamber when the piston is in a fully downstream position.

    摘要： A valve includes a basic body, control spool, sealing ring, and control cover. The control spool is received in the basic body to be movable along a longitudinal axis. The basic body includes a counter-sealing surface, connecting channel, and tank channel having at least one first annular groove surrounding the control spool. The control cover and at least one end face of the control spool facing toward the longitudinal axis delimits, at least in part, a control space. The control cover includes a sealing surface that abuts the counter-sealing surface of the basic body. At least one of the sealing surface and the counter-sealing surface includes a sealing groove that surrounds the control space in ring-like fashion. The sealing ring is received in the sealing groove. The connecting channel opens out into the tank channel and into the sealing groove.

    摘要： A hydraulic fluid de-aeration device for a hydraulically actuated variable valve actuation system is provided. The device includes a de-aeration bridge having a first end and a second end. The device includes a conical de-aeration chamber having an outer wall and a generally vertical center axis. The second end of the de-aeration bridge is offset from the center axis of the de-aeration chamber such that hydraulic fluid flowing from the de-aeration bridge is directed towards the outer wall of the de-aeration chamber. The device includes a cover with a vent hole for air that is expelled from the hydraulic fluid. A passage connected to the de-aeration chamber supplies the hydraulic fluid to a hydraulic fluid gallery of the variable valve actuation system.

    摘要： A hydraulic braking system includes: a master cylinder including: a pressurizing piston fluid-tightly and slidably fitted in a housing; a front pressure chamber located in front of the pressurizing piston and connected to a brake cylinder; and a rear chamber located behind the pressurizing piston; a rear-hydraulic-pressure control device connected to the rear chamber of the master cylinder and configured to supply control hydraulic pressure to the rear chamber; and an air bleeding device configured to perform air bleeding for an air bleeding target portion as at least a portion of the rear-hydraulic-pressure control device, in a state in which working fluid is prevented from being supplied to the rear chamber.
