A spring valve configured to provide automated movement of the control lever thereof so as to return the control lever to the first position. The spring valve includes a body having a first end and a second end configured to be releasably secured to pipes. The body has movably coupled thereto a control lever that is configured to be moved between a first position and a second position. The control lever is operably controlled with a torsion spring that is operably coupled therewith. The torsion spring includes a first end that is operably coupled to a spring end engagement member formed on the body. The second end of the torsion spring is operably coupled to control lever. Control lever includes tab member formed on the lower portion of the control member. The torsion spring is operable to apply torque to the control lever to return to its first position.

A faucet having a body extending from forward to aft ends to define a body cavity, the body includes an aft wall having faucet inlet ports, and a faucet outlet between the forward and aft ends; a push knob coupled to the body forward end; a cartridge fixed within the body cavity, the cartridge has a cartridge cavity with an aft seal seat, a cartridge outlet port forward of the aft seal seat, and a cartridge inlet port aft of the aft seal seat; a piston within the cartridge cavity, defining an aft seal lip: the piston is movable by the push knob from first to second positions, to move the lip and open the faucet; and the piston moves from the second to the first positions, to position the lip against the aft seal seat and close the faucet; and a linear damper, mounted to the body forward end.

A touch faucet contains: a body, a temperature control valve, a water control valve, and an actuation member. The body includes an inlet segment, an outlet segment, and a first cavity which has a first hole. The temperature control valve is housed in the first cavity and includes a water inflow portion configured to flow cold water and hot water, a mixing chamber in which the cold water and the hot water are mixed to form a mixing water, and a water outflow portion configured to flow the mix water. The water control valve includes an operation post touched to turn on the water control valve, such that the mixing water flows into the water outflow portion from the mixing chamber, and the actuation member partially exposes outside the body so as to be operated by a user to drive the operation post to move.

A mechanical system for calibration during a chemical feed process includes a ball valve that includes three openings. The ball valve is in communication with a lever, which when turned to a fill position, allows the filling of a drawdown cylinder for calibration. The ball valve automatically returns to its original default position within about a minute with a spring force automatically pushing it back to its start position.

A central tire inflation/deflation system (CTIS) with a novel valve that may deflate more quickly and may deflate to a lower pressure than the previously known central tire inflation/deflation system valves. Also, the present valve may not be temperature sensitive, at least because the present valve does not require trapped air behind a diaphragm to operate the valve. The present valve may be placed into existing CTIS's in place of existing valves, without modifying pneumatic lines of the existing CTIS's. Thus, the present valve may be operated by a single fluid flow line, receive pressure from the single fluid flow line, and exhaust to the single fluid flow line. A second communication line, either a pneumatic pilot line or an electrical line, is not necessary, which allows the present valve to be retrofit into an existing CTIS without adding weight or complication from additional components.

Disclosed is a system and valve assembly that can be used to promote the laminar flow of a variety of fluids and gases. In one embodiment, the valve assembly can be used to remove entrained water bubbles from a water supply. This, in turn, increases the density of water running through an associated water meter. This ensures that the water meter is not inaccurately including entrained air as metered water. The result is more accurate water readings and reduced utility bills. The assembly can be externally adjusted using an adjustment tool so as to increase or decrease the tension on an interior spring which, in turn, increases or decreases the rate at which the interior block oscillates.
