A valve for a vehicle provided between a transmission and an oil cooler for cooling transmission oil may include a valve housing in which a first inflow port connected to the transmission and an exhaust port connected to the oil cooler are formed on both sides facing each other and a bypass port connected to the transmission and a second inflow port connected to the oil cooler are formed at a position spaced apart from the first inflow port and the exhaust port along a length direction of the valve housing, and a control unit that is mounted inside the valve housing selectively connects the first inflow port to the exhaust port or the bypass port while expansion or contraction is performed depending on a temperature of the transmission oil, and selectively closes the exhaust port to control a flow stream of the transmission oil.

A dispensing system for dispensing cleaning product for hand sanitization comprises a cartridge having an internal reservoir for containing hand sanitization product, a nozzle configured in one of a plurality of key shapes, and a dispenser having a receptacle opening adapted to receive and engage the nozzle of the cartridge when the receptacle opening is configured in one of a plurality of key shapes corresponding to the key shape of the nozzle, the dispenser having a fluid communication passage for dispensing fluid for hand washing, whereby only cartridges and dispensers which have matched key shapes will engage each other for operative discharge of the hand wash cleaning product. The system includes a valve insert member which prevents leakage of fluid unless the nozzle key matches the receptacle opening. The valve insert member is in the form of a cup shaped member of elastomeric material, said member having a curved top having at least one slit having two slit edges, said slit defining a valve which is normally closed when the two slit edges are in mutual contact, but which slit edges separate when the curved top is penetrated, to thereby open the valve. Two slits can be provided in a cross-pattern.

To produce sealing plates (1) consisting of a plurality of sealing rings (3) connected by radial webs (2) by injection molding, wall-type guide elements (5) are arranged obliquely to the direction of flow in the mold channel (6) which is therefore initially largely constricted in the region of weld lines (15) formed by the convergence of the fronts of the divided plastic melt streams, said guide elements being moved out of the mold channel (6) during the further filling of same so that the strength is significantly improved in the region of the weld lines (15).

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.

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 method for manufacturing a self-sealing valve for an inflatable body such as a toy balloon is disclosed. The method comprises immersing a mold in an immersion bath of an elastomeric material in liquid form and heating the mold in a heating device until a hollow tube element of an elastomeric material with a proximal end, a distal end, a cylindrical portion at the proximal end, a flat portion at the distal end having two flat sides, and a transition portion between the cylindrical portion and the flat portion is formed. The cylindrical portion is open at the proximal end and the flat portion is closed at the distal end with an opening on at least one of its flat sides. The valve is inserted in an inflatable body with the flat and transition portions of the hollow tube element located inside the inflatable body.

A self-energized programmable timer valve is provided in embodiments of this invention that can be used in watering and other systems, such as lawn watering systems and agricultural watering systems. The invention provides one or more components that serve the functions of a clock, a valve and an energizer (e.g., turbine) (i.e., a clock function, a valve function, and an energizing and/or turbine function) to control the flow of media (e.g., water) through the valve. Exemplary components comprise a programmable clock apparatus comprising a mechanical clock mechanism and a mechanical mainspring, the programmable clock apparatus capable of opening and closing a control valve system by using a first connecting apparatus; the first connecting apparatus which converts the rotational movement of an of an hour dial and a minute dial to a linear movement of a valve plug component to open and close the control valve system and control the flow of media through it; and a turbine apparatus comprising a turbine shaft that has a turbine impeller on one end that is capable of turning when water flows through the control valve system, wherein when the turbine impeller turns its rotational energy is transferred to the mechanical mainspring of the programmable clock apparatus.
