    Abstract: Presented are embodiments of pressure relief valves for use in water supply systems to prevent damage thereto caused by over pressure resulting from freezing of the water therein. In one embodiment the pressure relief valve is included in an electromechanical solenoid controlled water valve particularly useful in appliances such as washing machines, water heaters, refrigerators, etc. Prior to the main valving member, a spring loaded pressure relief valving member is included. Once the pressure within the valve exceeds the spring force, which is set below the failure pressure of the water supply system and the valve, the pressure relief valving member opens to allow a flow of water therethrough. Alternatively or additionally, a temperature active device such as a bi-metal disc is interposed between the spring and the pressure relief valving member to provide actuation thereof below a predetermined temperature.

    Abstract: A control circuit for a washing machine that avoids contact bounce short circuit failures is provided. A washing machine that utilizes an induction motor including a starting winding used to start rotation of the motor at the beginning of a cycle. Such washing machines require that the motor be operated in both directions during different cycles. To enable such operation, a mechanical timer uses a pair of single pole, double throw switches in a switching assembly to reverse the L1 and neutral connections to the starter winding. To avoid the contact shorting problem, the control wiring runs either the L1 or neutral side of the voltage source, or both, through the centrifugal switch to open the input contact(s) once the motor has reached its operating speed. Then, if the switching assembly has L1 and N contacts touching at the same time, it will not result in a dead short.

    Abstract: A butterfly valve having a plastic body with a one-piece valve member formed of thermoplastic elastomer with an integral hub with torque transmitting surfaces which are engaged by lugs on a rigid shaft received in the hub and the shaft is journalled for rotation in the valve body. The valve member has integral thin blade portions extending in opposite directions from the hub with a thickened rim formed about the periphery of the blade with the edge of the rim preferably chamfered. The preferred butterfly member has integral stiffening ribs extending centrally from the hub along the blades to the rim.

    Abstract: A gas system, such as an appliance or a building has a pressure sensor intermediate a master solenoid valve and at least one valve, wherein when the at least one valve is closed, shut or off, and the master solenoid valve is off, the pressure sensor senses pressure and if pressure drop over a given time exceeds a predetermined amount, an alarm condition is identified (indicating a leak). The master solenoid valve may be maintained shut until the leak is addressed.

    Abstract: Embodiments of a valve having a housing including an inlet, an outlet, and an interior chamber in fluid communication with the inlet and the outlet are disclosed. The valve also includes a seat fitting having a first screen held in place by a first retainer ring. The seat fitting includes a valve seat. The valve further includes an outlet fitting having a second screen held in place by a second retainer ring. The second retainer ring includes a plurality of ribs extending from a ring body such that the plurality of ribs create a gap between the ring body and the second screen. Further, the valve includes a valve plug configured to selectively engage the valve seat to open and close a passage between the interior chamber and the outlet. The seat fitting is contained at least partially within the outlet fitting to define the outlet of the housing.
