Abstract: There is disclosed a pressure regulating valve which effectively reduces a noise of a fuel pressure regulating valve without relation to a flow amount of a fuel. In this valve, a flow collision preventing member (35) is fitted to an upper end opening portion of a bush (26), and an upper portion of the flow collision preventing member (35) is protruded to a side of a valve body (33) rather than a valve seat (28) (an upper end surface of the bush (26)). A plurality of flow passages (36) for flowing the fuel in an axial direction thereof (in a downward direction) along an inner peripheral surface of the bush (26) are formed in an outer peripheral portion of the flow collision preventing member (35) with a uniform interval. A runoff recess portion (37) running off a protruding portion of the flow collision preventing member (35) is formed in the valve body (33) positioned immediately above the valve seat (28).

Abstract: A motorized rotary water valve has an integrally formed one piece motor housing and emergency bypass channel. A solenoid operated valve is integrally provided on the bypass channel and is spring biased to the open position upon shut off of electrical power to the solenoid.

Abstract: A device is provided for distributing a fluids from different sources to different destinations. The device receives fluids from a plurality of different sources and distributes the fluids out of a port to a destination. The device also receives fluid from the destination and transfers the fluid to another port out to another destination.

Abstract: A bypass assembly is provided for bypassing a water softener. The bypass assembly includes a bypass valve, a shut off valve at the input to the water softener, and a shut off valve at the output of the water softener. The shut off valves are positioned between the bypass valve and the tank of the water softener. A t-shaped fitting is used to interconnect the water supply, bypass valve and first shut-off valve and a second t-shaped fitting is used to interconnect the water discharge port, the bypass valve and the second shut-off valve. The t-shaped fittings are provided with double street ends to facilitate interconnection of the t-shaped fittings to corresponding valves.

Abstract: An improved valve is provided for blanketing and maintaining the vapor space of a tank with inert gas at a set pressure. The valve is of the type that incorporates a pilot valve that operates in response to sensed tank vapor space gas pressure. The opening and closing of the pilot valve controls the opening and closing of an associated main valve which admits pressurized inert gas into the tank from an inert gas supply to maintain the tank set pressure. The valve permits one to externally adjust internal components of the pilot valve after valve assembly. Also, the valve provides for pressure balanced operation that achieves a consistent opening pressure over the allowable range of inlet gas supply pressures.

Abstract: Disclosed is an air volume regulator valve for an air distribution apparatus for heating, ventilating and air conditioning systems having a first open position, a closed position and a second open position and means for maintaining relatively constant volume of airflow under changing air inlet pressures. The valve may be cylindrical or flat and has a "dead band" feature to allow the valve to better assist in controlling temperature of a room or plenum chamber to be heated or cooled.

Abstract: A fluid flow regulator including a servo valve assembly and a throttle valve assembly. The servo valve assembly includes a pair of double acting actuators, biased in one direction by an adjustable spring, contoured ports and piping passageways to the ports and to other chambers of the assembly. The actuators are effectively connected together and function to oppose each other. The chambers formed between the two actuators and the respective cylinder chambers formed on the exterior ends of each actuator are used for pressure sensing purposes. Each individual actuator may be comprised of up to three piston lands with adequate separation between to form chambers for fluid transfer purposes. Any leakage or servo flow entering these chambers would be communicated by passageways to appropriate interface ports on the regulator. Due to its sensitivity, the servo valve assembly effects a desired action by variably restricting the flow or pressure in a passageway controlled by the throttle valve assembly.

Abstract: A valve and particularly a safety valve for use in controlling flow from a well in which an external motor is utilized to shift the actuator of a valve such as a ball valve. The reciprocating rod of the motor is protected by resilient means between the crosshead attached to the motor and the reciprocating actuator. The actuator is latched when the valve is in the open position so that it cannot be moved to closed position except by movement of the reciprocating motor. The valve and seat assembly are designed to be replaced as a unit and can be fabricated as a subassembly with the valve in exact open alignment when the reciprocating actuator is in full valve open position as determined by a stop against which the valve member bottoms.
