20080251136 | AIR CONTROL REGULATOR FOR COMBUSTION CHAMBER - An air control regulator regulates the amount of air flowing into the inlet of a combustion chamber by causing flowing air to support a disc located in the air passage against the force of gravity. Air passes around the edges of the disc and is channeled into a plurality of airflows by ovoid depressions in the inner surfaces of the regulator forming a venturi chamber. By regulating the airflow into the combustion chamber, combustion efficiency is improved. | 10-16-2008 |
20090020169 | Easy-type water pressure reducing apparatus - An easy-type water pressure reducing apparatus comprises a connecting tube having a bore extending through an inlet end and an outlet end. The bore has an annular seat with a smaller-diameter inlet chamber integrally extending at both sides to which a movable element with an inlet port to receive a spring element is mounted. The movable element also includes positioning guide blocks to fit to water-guiding vents of the inlet chamber, and a ringed groove with a sealing ring to abut tight against the inlet chamber, forming a back-and-forth movable positioning space there-between. Therefore, when water pressure at the outlet end is larger than that at the inlet end, water flow blocked by a water plug of the movable element will push the movable element towards the inlet end, compressing the spring element and closing the water-guiding vents gradually to reduce the water flow and stabilize the water pressure thereby. | 01-22-2009 |
20090260697 | Valve Body with Dual Sense Mechanism - A gas regulator includes an actuator, a regulator valve, and a secondary device.

The Pitot tube has a first branch having an end connected to the actuator to place the actuator control cavity and diaphragm in fluid communication with downstream pressure within the outlet for maintaining the outlet pressure at an actuator setpoint pressure. The Pitot tube also has a second branch having an end connected to the secondary device to place the interior of the secondary device in fluid communication with downstream pressure within the outlet for responding to changes in the downstream pressure when the outlet pressure diverges from a predetermined normal operating pressure range. | 10-22-2009 |
20090301577 | Combination Venturi Check Valve - Disclosed herein is a combination venturi check valve for introducing a composition, such as ozone, into the fluid circulation line of a swimming pool, spa, and/or other recreational body of water.

An inner side spring presser ( | 11-12-2015 |
20150330094 | IN-FLOOR POOL CLEANING SYSTEM - A distribution valve of an in-floor pool cleaning system is provided. The distribution valve includes a housing having an inlet port and a plurality of outlet ports. A turbine within the housing rotates about a shaft in response to fluid flowing through the inlet port. The turbine is releasably coupled to a gear mechanism, and the gear mechanism is releasably coupled to a distribution valve disk, the disk having an aperture therein. As the turbine rotates, the gear mechanism also rotates and drives the rotation of the disk around the shaft. The rotation of the disk sequentially places the aperture over one of the plurality of outlet ports, thus allowing fluid to flow out of the outlet port over which the aperture is positioned, but restricting fluid flow into any of the outlet ports that are covered by the disk. | 11-19-2015 |
20150330514 | SOLENOID VALVE - A first valve chamber, which receives a valve assembly of a tank closing solenoid valve, and a second valve chamber, which receives a valve assembly of a pressure responsive valve, are formed between a first flow passage and a second flow passage of a first housing by fitting a second peripheral wall of a second housing into a radially inner side of a first peripheral wall of the first housing. Thereby, it is not required to heat-weld and bond between a connecting end surface of the first housing and a connecting end surface of the second housing. | 11-19-2015 |
20150355642 | FLUID REGULATOR HAVING A BIASED PRESSURE SENSE TUBE - A fluid regulating device includes a valve body, a control element, a control assembly, and a sense tube. The valve body has an inlet, an outlet, a valve port, and a control element adapted to be displaced relative to the valve port to control the flow of a fluid between the inlet and the outlet. The control assembly is operatively coupled to the control element and includes a diaphragm disposed adjacent a diaphragm chamber. The sense tube has a first end, a second end, and a sense hole. The first end is positioned to communicate with the diaphragm chamber, the second end is disposed adjacent the outlet, and the sense hole being formed in the sense tube between the first end and the second end and being oriented along an axis that is angled relative to an axis of the outlet. | 12-10-2015 |
20160103455 | HYDRAULIC VALVE HAVING PRESSURE COMPENSATED FLOW CONTROL - A hydraulic valve having a hollow valve body configured with a supply port and a supply port. The hollow valve body has several different internal diameters. An elongate spool is reciprocally received in the body and has a large diameter annular spool ring oriented adjacent a sensing land inside the hollow body forming a gap with a sensing land to cause a pressure drop across the gap in response to a flow of fluid from the pressure port through the gap to the control port. A servomotor reciprocally drives the spool lengthwise of the valve body against a spring force. When flow of fluid occurs in response to servomotor movement of the spool, the pressure drop across the gap combined with the spring force determines a pressure balanced location to which the spool is moved. | 04-14-2016 |
