    Abstract: An axle assembly can include a housing defining a reservoir and cylindrical bore open thereto. A clutch can selectively transmit torque between input and output members. A first inlet/outlet of a pump can be in fluid communication with the reservoir and define first threads coaxial with the cylindrical bore. The pump can be configured to pump fluid from the first inlet/outlet to an actuator of the clutch via a second inlet/outlet. The filter can include a base, port, and filter element. The port can define second threads that threadably engage the first threads. The base can be fixedly coupled to the port and include a cylindrical wall coaxial with the second threads. A seal member can form a seal between the cylindrical wall and the cylindrical bore when the first and second threads are engaged. The filter element can be disposed between the reservoir and the first inlet/outlet.

    Abstract: A fluid storage reservoir that creates a regenerative loop inside the reservoir to maintain a pressurized main suction chamber of the hydraulic fluid reservoir is provided. This reservoir includes two separate chambers which are operably fluidly connected by one or more check valves. In the main suction chamber, the design arranges the return flow larger than suction flow in order to pressurize this chamber. This pressure can be adjusted by the check valve setting. This regenerative reservoir can provide sufficient pressure when large system flow occurs.

    Abstract: A variable valve timing control device includes a drive-side rotational body, a driven-side rotational body, a connecting bolt coaxially disposed with a rotary axis and connecting the driven-side rotational body to a camshaft, the connecting bolt formed with an advanced-angle port and a retarded-angle port from an outer circumferential surface of the connecting bolt through an inner space, a valve unit disposed at the inner space of the connecting bolt, and a check valve provided at an upstream in a supplying direction of fluid relative to the valve unit. The check valve includes a seat member formed with at least one circulation port at a position being away from the rotary axis; and a valve body configured to close the circulation port at a downstream in the supplying direction of the fluid relative to the seat member, the valve body including an opening portion about the rotary axis.

    Abstract: 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.

    Abstract: A part of kinetic energy during lowering of a slide of a press machine is converted into oil hydraulic energy by a first oil hydraulic cylinder, and the converted oil hydraulic energy (hydraulic oil having boosted first system pressure) is stored in a first accumulator. The hydraulic oil having the first system pressure stored in the first accumulator is discharged in knockout process, a second oil hydraulic cylinder that functions as a knockout cylinder is raised to perform knockout operation of a product worked by the press machine. Consequently, it is possible to perform knockout operation without using a dedicated driving source such as an oil pressure source and an air pressure source, and provide a low-cost hydraulic knockout device.
