Abstract: A manually operated switch for a faucet has a body, an inner pipe, a switching valve assembly. The body is hollow. The inner pipe is located inside of the body and has a flowing way. The flowing way is formed through the inner pipe. The switching valve assembly is slidably mounted inside of the flowing way of the inner pipe and extends out the body. When the switching valve assembly closes the flowing way of the inner pipe, the water pressure will keep the switching valve assembly closed. After the water pressure applied to the switching valve assembly is released or dismissed, the switching valve assembly returns back to an original position so that the flowing way is opened. The opening and closing flowing way can manually control the way of water flowing so that a user may not be scared or burned by the water.

Abstract: A drip resistant dispensing valve for fluids is disclosed, which provides a dispensing outlet configured to minimize the tendency for fluid to drip from the valve following a dispensing operation. The dispensing outlet exhibits curved interior surfaces and a curved outlet face construction; the face situated a distance away from the valve body. Such construction assists in minimizing the retention of fluid on the surfaces of the dispensing outlet, and migration of the fluid to surfaces outside of the dispensing outlet that could tend to promote growth of biological contaminates and/or provide additional surfaces that could pool fluid following a dispensing operation and thereafter drip from the valve. A shell is provided around the dispensing outlet to assist in avoiding contamination of the valve and of the fluid being dispensed through the valve, and to aid in positioning a receptacle for receiving fluid from the dispensing valve.

Application, for example, to pneumatic machining machines.

Abstract: A method and apparatus for servicing a pressurized system is described. A purge fitting can be used to vent the pressurized system. Venting can release a gas, such as air, from the system. The pressurized system can be a climate control system (e.g., an air conditioning or refrigeration system), a brake system, a hydraulic system, or a service device for servicing a climate control system. The purge fitting allows air that may be trapped in the pressurized system to be vented by depressing a purge actuator, such as a purge button attached to the fitting. The air can be vented from an opening adjacent to the actuator or other orifice. By purging air directly from the system, the amount of air introduced into the system during servicing can be minimized. The invention also features a coupling member that can be compact in size.
