A trigger sprayer valve assembly that has a conical flange that controls the flow of liquid in a downstream direction through a liquid passage of the trigger sprayer. The valve is constructed with an elongate stem or shaft that facilities the assembly of the valve into the trigger sprayer and a positioning plug that solely holds the valve in a centered position in the liquid passage of the trigger sprayer.

A wireless tire pressure sensing system based upon a Schrader valve design is provided. The system includes a valve body, a valve pin and a compression element for sealing engaging the valve body and the valve pin to maintain tire pressure. A pressure sensing device mounted within the valve body and connected to valve pin senses the pressure within the tire and provides its signal to the valve pin. The valve pin is adapted as a component of an antenna that transmits a wireless pressure signal to a remote receiver / transmitter mounted on the vehicle. The receiver / transmitter transmits a corresponding signal to a vehicle control system that generates a warning signal when the tire pressure is below a threshold safety value.

Liquid fuel injectors are provided. The liquid fuel injectors allow the injection of a fine spray of liquid fuel. The liquid fuel injectors utilize a schrader valve movable between an open position and a closed position. When the schrader valve is in the closed position fuel flow is blocked and purge gas is allowed to flow through the fuel injectors. When the schrader valve is in the open position, the flow of purge gas is blocked and fuel is allowed to flow through the fuel injector. In this manner, the fuel injectors provide for an immediate and automatic purge of the fuel lines when the fuel flow is shut off.

A fire safety fluid flow device for engagement with a Schrader valve including a sliding valve a housing having a fluid path therethrough and a pressing member. The pressing member presses against the sliding valve of the Schrader valve when engaged therewith to allow fluid flow through the Schrader valve. The pressing member continues to maintain the sliding valve in an open position when the device is below a predetermined temperature and connected to the Schrader valve. The pressing member is configured to no longer press against the sliding valve of the Schrader valve at and above the predetermined temperature to allow the sliding valve of the Schrader valve to thereby stop fluid flow through the Schrader valve.

By a universal valve connector for inflation valves of vehicle tires (Sclaverand, Dunlop-Woods, or Schrader), whose connector consists of a connector housing (368), which partly is connected to a pressure source, preferably a hand or foot pump, and which partly has a coupling hold (5) with a diameter corresponding to the diameter of the valve, which is to be connected, where the coupling hole is equipped with a securing means for securing on the valve, plus a sealing means against valves of different sizes. This to is achieved by the sealing means (366) being mounted coaxially in the connector housing (368) and being established on at least two parallel, separate levels, having the center line (4) of the connector housing (368), which is coaxial to the center line of the valve, as its normal, where the minor diameters of the sealing means approximately correspond to the major diameter of the current valve dimensions, on which the connector is mounted when used, that the sealing means (366), closest to the opening (8) of the coupling hole (5) in the connector housing (368) has the biggest minor diameter, while the sealing means (366) farthest from the opening (8) of the coupling hole in the connector housing (368) has the smallest minor diameter, and diameters between the extremes are lying corresponding separate distance between these extremes. The valve connector has the possibility of automatically adjust itself to the valve in question and if needed to activate the central core of a Schrader valve. Also, it is possible to use the connector with existing pumps.

A multipurpose tire valve tool is provided for the purposes of maintenance of a Schrader valve and for replacing the tube of a pneumatic tire. The tool comprises a valve core removal key, a valve stem tap arm, a first air inlet end, and a second valve stem attachment end. Through the body of the tool is an air conduit and an internal valve core post for depressing the same. A check valve along the air inlet end allows air to be communicated into the tool, whereby the air flows therethrough and into an attached Schrader valve for filling the tire tube while the tool is thereattached. The tool facilitates removal of the valve core, cleaning of the valve stem threads, and filling the tire or tire tube with air while the tool maintains the position of the valve stem through the rim.

A welding cable connector system having a male connector and a female connector. The male connector includes a first conductive body for conveying welding power. The male connector also includes a first sealed passageway disposed coaxially of the first conductive body for conveying shielding gas, and a first Schrader valve configured to stop flow of shielding gas when the male connector is not engaged. The female connector includes a second conductive body for conveying welding power. The female connector also includes a second sealed passageway disposed coaxially of the conductive body for conveying shielding gas, and a second Schrader valve configured to stop flow of shielding gas when the female connector is not engaged. The male and female connectors are mutually engageable to conduct welding power and shielding gas therethrough. The first and second Schrader valves seal the flow of shielding gas when the connectors are not mutually engaged.

A hose attachment device for use in combination with a source of pressurized gas or liquid for clearing HVACR drain lines. The device includes a cap having an interior cavity extending from an open bottom end that is sized for engaged receipt of an open-ended drain line extension. One embodiment of the device includes a hose extending through the top of the cap and having a fitting at the proximal end of the hose (extending from the top of the cap) that is sized for attachment to the pressurized source. A valve fitting at the distal end of the hose is sized for engaged receipt of a male valve stem, such as a Schrader valve. Another embodiment of the invention includes a valve fitting extending through top of the cap. A further embodiment of the invention includes an upper component and a lower component forming the cap, wherein the upper component is securable to a nozzle of a garden hose and the bottom component is securable to an open-ended drain line extension.

The invention discloses a temperature-sensing anti-scald valve. The valve comprises a valve cover, a fluid channel is formed in the valve cover, a fluid inlet and a fluid outlet are formed in the twoends of the fluid channel respectively, a cavity and a channel hole are formed in the fluid channel, a magnetic elastic mechanism is arranged below the cavity, a sealing element sleeves the outer sideof the magnetic elastic mechanism, the sealing element, the cavity and the channel hole form a sealing cavity, and a fluid flows into the channel hole from the fluid inlet, enters the cavity throughthe sealing cavity and finally flows out of the fluid outlet. When the magnetic elastic mechanism is heated, the magnetic elastic mechanism loses magnetism and moves upwards under the action of elasticity to drive the upper surface of the sealing element to be attached to the lower surface of the cavity, and the lower surface of the cavity is sealed to prevent the fluid in the sealing cavity fromflowing out. The magnetic elastic mechanism is used for switch-on and switch-off of the temperature-sensing anti-scald valve, so that the valve is used for limiting flowing of liquid or gas exceedinga specific temperature.
