Abstract: A valve is provided with one inlet and two outlets with one of the outlets being normally closed by a valve in the form of a film disc carried by a flexible blade. A magnetic pad secured to the blade is attracted by the proximity of an actuator carrier magnetic element to cause the flexing of the blade to open the normally closed outlet and to close the normally open outlet. The actuator may be either thermally or electrically actuated and is suitable to override a bleed thermostat to permit warm-up of an overcooled area or to cause a switchover in operation between a heating and cooling mode by connecting the appropriate bleed thermostat so as to control the inflation of the bellows.

A magnetic pad secured to the blade is attracted by the proximity of an actuator carrier magnetic element to cause the flexing of the blade to open the normally closed outlet and to close the normally open outlet. The actuator may be either thermally or electrically actuated and is suitable for use in a VAV system with thermostatically controlled bellows to override a bleed thermostat to permit warm-up of an overcooled area or to cause a switch over in operation between a heating and cooling mode by connecting the appropriate bleed thermostat so as to control the inflation of the bellows.

Abstract: A duct pressure powered air volume controller controls the flow through a terminal responsive to the differential pressure across a nozzle plate, the selected ventilation requirements, and the temperature of the supplied air, the zone and the setpoint.

Abstract: An improved inlet duct for a cartridge type control valve which includes, a cup-like member having a bottom wall and a side wall defining the fluid transfer chamber in said control valve, is formed from a tubular member having a J-shaped configuration inverted in assembled position in the control valve, the tubular member has an inlet leg and an outlet leg continuous with the inlet leg, the inlet leg is staked in fluid tight engagement in the bottom wall of the cup-like member a predetermined distance from the side wall and defines an inlet port in the staked position extending to the exterior of the cup-like member, and an adhesive is applied between the bottom wall of the cup-like member and the exterior of the inlet leg to insure maintaining the said fluid tight seal, the outlet leg has an outlet port and in assembled position is so cantilevered into the fluid transfer chamber that the outlet port faces the bottom wall in the center line of the control valve, and an inwardly directed indentation in the sid

Abstract: A valve assembly for a dispensing head with a conventional gooseneck type dispensing spout for filling carafes and the like type containers has a single bore in the center line of the dispensing head for mounting the dispensing spout and operating elements of a valve for controlling the flow of the fluid being dispensed to the inlet or lower end of the dispensing spout, the lower end of the dispensing spout forms the valve head for the valve maintained normally closed, and manual actuating device is provided to lift the dispensing spout so as to move the valve to open position.

Abstract: An air gap drain module for use with the dispensing head of a reverse osmosis dispensing system for potable water has an inner waste water tube and an outer drain tube which are disposed concentric to each other at one end and for a portion of the length of the inner tube adjacent the concentric end. An air gap in the form of spaced slots is provided adjacent the concentric end of the drain tube and a closure is connected to the common end of the waste water tube and drain tube with an annular flange or skirt thereon in assembled position disposed to extend between the waste water tube and the drain tube to form an annular passage about the waste water tube and direct the movement of process water issuing from the concentric end of the waste water tube into the drain tube. The closure forms a chamber or trap with the adjacent end of the waste water tube which in conjunction with the spaced slots prevent back flow into the waste water tube.

Abstract: A thermally actuated modulating valve preferably for fail safe energy conservation systems includes a valve body having, a main inlet for cold source water, an outlet for heated water, and a fluid transfer chamber connected for delivering heated water to the outlet. A proportioning slide valve assembly formed in said valve body connected to the main inlet to receive cold water therefrom includes, spaced outlets, a slide valve to vary the volume of cold water delivered respectively through the spaced outlets, one of said spaced outlets for delivering varying volumes of cold water to be heated. The valve body has a mixing chamber connected to one of the spaced outlets of the proportioning slide valve assembly to receive cold water therefrom, an inlet for the heated water from the other of said spaced outlets, an outlet for delivering the mixture of cold and heated water to the fluid transfer chamber.

Abstract: A thermally actuated phase change operated control valve particularly adapted for use with heat pump systems has a valve body having a bore therein defining a fluid flow chamber, said valve body having an inlet port at one end and spaced and sized outlet ports in the medial wall thereof so that a valve head slidably disposed in the fluid flow chamber will in the calibrated position of the valve head maintain a predetermined minimum flow of fluid from said inlet port through the respective outlet ports.

Abstract: A thermally actuated phase change operated control valve has, a valve body with a bore therethrough the walls of which define a valve chamber, the valve body has a manifold assembly about the valve body and a medially disposed first port means in the valve body connects the valve chamber with the manifold assembly. Spaced second and third port means in the valve body respectively disposed on opposite sides of said first port means permit valve head means slidably disposed in said valve chamber for movement relative said first port means to direct fluid either from the valve chamber to one or the other of said second and third port means or vice versa depending on whether the control valve is operated as a diverter valve or as a mixing valve or if desired one of the spaced second or third port means can be rendered inoperative and the control valve can be operated as a thermal check valve.

Abstract: A dispensing head for use in a fluid dispensing system has a base member made from an inert plastic material with locking guide means at the lower section thereof and boss means at the upper section. The boss means has a shoulder a predetermined distance from the locking guide means and a control valve cavity which extends into the base member from the upper surface of the boss means so as to communicate with an inlet for fluid to be dispensed and an outlet for dispensing said fluid respectively disposed in the base member a spaced distance therefrom. A guard member also made of an inert plastic material has a connecting section and a shield section. The connecting section forms a shaped cavity with locking guide grooves on the inner wall of the connecting section so that the guard member in assembled position will operatively engage locking guide means at the lower end and a shoulder at the upper end of the base member.
