A dispensing tap for liquids includes a body connected to the neck of a container, a dispensing head with an outlet or mouth, and a throat connecting the body to the dispensing head. A shut off valve is configured for sealing engagement with the mouth of the dispensing head, and a piston is axially guided within the dispensing head. The piston includes a peripheral seal slidably engaged with an interior surface of the dispensing head, and a valve stem coupled to the shut off valve. The piston is selectively actuable between a normally closed position an open position. A vent is in communication with an interior of the body and the vent is opened and closed with movement of the piston and shut off valve.

A dosing unit for dosing fluids includes a fluid guiding module having a fluid inlet and a fluid outlet, a solenoid valve for controlling or regulating a fluid flow through the fluid guiding module, and a dosing tip, the fluid outlet of the fluid guiding module leading to the fluid inlet of the dosing tip, and the dosing tip having an elastic, self-closing outlet nozzle. Furthermore, a dosing station and a dosing tip are specified.

A sealed hydraulic stop valve for caliper guide system of an air disk brake system provides a means of continuous maintenance and lubrication. The system includes a tubular guide pin, a cap, a sealed hydraulic stop valve, and a plurality of lubricating grooves. The tubular guide pin attaches a caliper head to a carrier of the air disk brakes. The lubricating grooves inject grease into the system and are radially distributed about the tubular guide pin. Each lubricating groove normally and externally traverses into the tubular guide pin. The cap and the stop valve seal off the tubular guide pin and allow for grease injection to the lubricating grooves. The cap is concentrically positioned about the tubular guide pin. The stop valve is adjacently integrated into the cap, opposite to the tubular guide pin. Resultantly, the stop valve is in fluid communication with each of the lubricating grooves.

Provided is a safety valve (10) comprising a body (12) which defines an incoming fluid passage (14) and a return fluid passage (20). The incoming fluid passage (14) generally enables a fluid to pass from a fluid reservoir (18) through the body (12) to the tool head (16). The return fluid passage (20) generally enables a fluid to return from the tool head (16) through the body back to the fluid reservoir (18). The body (12) further comprises a diverter (22) which is displaceable between an active position and an inactive position. When the diverter (22) is in the active position, the diverter (22) redirects the fluid via a shunting passage (24) from the incoming fluid passage (14) to the return passage (20) to prevent operation of the tool head (16).

A refrigerator includes a main body, a dispenser configured to supply water to the outside of the main body, a water supply flow path connecting the dispenser to a water source; and a valve assembly disposed on the water supply flow path, wherein the valve assembly comprises an elastic member having an outlet whose diameter is reduced by an elastic force, when water is no longer supplied to the valve assembly, so that water remaining in the inside of the water supply flow path is kept by the surface tension of the water.

A control mechanism locks open a spring-loaded valve and automatically releases the spring-loaded valve to close upon a predetermined lesser weight load being applied. The spring-loaded valve includes a flow valve, a valve lever that pivots between open and closed positions, and a valve spring that biases the valve lever to the closed position. The control mechanism includes a pivotal release lever having an engagement arm and an opposite load arm, and a release spring that biases the release lever from a blocking position with the engagement arm retaining the valve lever in its open position to a release position with the valve lever free to pivot past the engagement arm and to the closed position under the valve spring force. The load arm includes an additive-container support for a load of an additive fluid to be mixed with a carrier fluid whose flow is controlled by the valve.

A safety faucet includes: a discharge pipe which has a hot water discharge path formed therein; a packing which moves up and down inside the discharge pipe; an operation shaft which is fixed to the packing; an upper cap which covers an upper opening of the discharge pipe, and has an upper cap through-hole formed in a center thereof to expose an upper end of the operation shaft; a lever which is rotatably coupled to the upper end of the operation shaft, and has an auxiliary operation hinge hole formed in an upper end thereof; and a safety member from which an auxiliary operation hinge shaft inserted into the auxiliary operation hinge hole is protruded, and has a cap contacting part formed in a lower end thereof to meet with an upper surface of the upper cap to form a support point.
