A water control valve with offset valve core has a main body with a flowing slot, the circumferential wall of which is formed with a water inlet and outlet. An offset rotary valve core is configured offset inside the flowing slot and has a rotary shaft and a water stopping seat. The face of the water stopping seat faces the circumferential wall and has a sealing ring. When the water stopping seat rotates along with the offset rotary valve core and is aligned with the inlet, the sealing ring is pressed against the circumferential wall to close the inlet, thus forming the water stop mode. The rotary shaft and the circumferential wall of the flowing slot define a flowing space. The flow from the inlet must pass through the flowing space and exit through the outlet. A dialing component is used to connect and drive offset rotary valve core.

A water faucet includes a first pipe, a housing and a first sealing ring. The first pipe includes a first sidewall, a second sidewall, a third sidewall and a first sliding portion. The first pipe includes a first accommodate space and an inlet. The housing includes a top wall, a second pipe and a second sliding portion corresponding to the first sliding portion. The second pipe includes a fourth sidewall connected with the top wall to form a second accommodate space and an outlet. When the first sliding portion slides to a first position, the first sealing ring is located between the fourth and the second sidewall to prevent water flowing between the first pipe and the housing. When the first sliding portion slides to a second position, water from the inlet can flow to the outlet via the first accommodate space, the though hole and the second accommodate space.

A closure element for a fluid end assembly that has two or more recessed grooves formed in its outer surface. The grooves are axially offset. A seal is placed in one and only one of the grooves. As wear occurs, the seal is relocated to one of the other grooves. Instead of a series of axially offset grooves in a single closure element, a kit may be formed from two or more otherwise identical closure elements, each with a single recessed groove at a different axial position. Another closure element has a series of ledge-like surfaces defining spaces within which a seal may be received. One outer surface surrounds one or more of the other surfaces. A seal is placed in one and only one of the spaces. As wear occurs, the seal is relocated to one of the other spaces.

The present disclosure includes a retaining ring for a valve plug assembly. The retaining ring includes a first ring portion having an inner surface with a central axis extending along a circumference of the first ring portion, and a rib disposed on the inner surface of the first ring portion and offset from the central axis. The retaining ring also includes a second ring portion having an inner surface with a central axis extending along a circumference of the second ring portion, and a rib disposed on the inner surface of the second ring portion and offset from the central axis. The second ring portion is coupled to the first ring portion such that each of the ribs disposed on the inner surfaces of the first and second ring portions are configured to mate with a groove of a valve plug.

Disclosed is a spool valve to valve a fluid between at least one inlet port and at least one outlet port, having a bore with a spool operably associated therein. The bore has one or more inlet ports and at least one outlet port. Located in the bore is at least one in-bore seal, the seal fluidly sealing on a seal outer diameter to an inside diameter of the bore, and selectively fluidly sealing on a seal inside diameter to a spool outside diameter. Present also is at least one spacer located in the bore, adjacent the at least one in-bore seal having a fluid communication from a spacer internal diameter to a spacer external diameter with at least one inlet port, or the at least one outlet port. The spool moves to allow or prevent flow from an inlet port to outlet port.

Transmissions, filter assemblies for transmissions, and valve assemblies for transmissions are disclosed herein. A transmission includes an input shaft, an output shaft, and a hydraulic system. The input shaft is configured to receive rotational power supplied by a drive unit. The output shaft is coupled to the input shaft and configured to provide rotational power supplied to the input shaft to a load. The hydraulic system is configured to supply fluid to one or more fluid demand devices coupled between the input shaft and the output shaft in one or more operating modes of the transmission. The hydraulic system includes a filter assembly having a filter element and a valve assembly fluidly coupled to the filter element.

A relief device in air pump includes a main body defining an interior space and a discharge passage fluidly communicating with the interior space. The discharge passage is selectively closed and opened by a valve device. The valve device is movable in the discharge passage. The valve device includes a first sealing portion and a second sealing portion selectively engaging with the discharge passage. The valve device is movable between a first position in which one of the first and the second sealing portions engages with the discharge passage and a second position in which the other of the first and the second sealing portion engages with the discharge passage. The discharge passage has a length measuring from the first end to the second end thereof, which is smaller than a length which measures a separation distance between the first and the second sealing portions.

The disclosure herein generally relates to flow control valves having mechanisms to prevent, inhibit, reduce the likelihood or extent of, and/or protect against erosion of components of the flow control valve, for example, due to the effects of leakage flow.

A solenoid valve with a hard seal structure includes a valve body having a fluid passage and an accommodating cavity, and a valve assembly mounted inside the accommodating cavity. The valve assembly includes a fluid inlet seat, a valve core cooperating with the fluid inlet seat, and a driving mechanism for driving reciprocating motion of the valve core. The fluid inlet seat has a guide hole that allows the value core to stretch therein, a middle section of the fluid inlet seat has fluid inlet holes, and a lower section of the fluid inlet seat has a valve core fluid passage and a fluid passage slant located at the valve core fluid passage. The valve core includes a bigger-diameter section, a slant section, a smaller-diameter section and a valve core end slant sequentially arranged from up to down.
