|---|
| 137505140 | Bias variable during operation | 8 |
| 20090301581 | Pressurized gas containing system - A pressurized gas containing system has a cowling and mounting ring which supports a valve and regulator on a cylinder containing gas under pressure. | 12-10-2009 |
| 20130255801 | FLUID SUPPLY DEVICE - A fluid supply device includes a fluid supply source, a valve, a differential-pressure generator, and a pressurizing device. The valve includes a casing, a displacement member that divides an inside of the casing into a first valve chamber and a second valve chamber, the displacement member being displaced by a pressure of a fluid being exerted on a front main surface and a back main surface of the displacement member, a first opening provided in the first valve chamber, a second opening provided in the first valve chamber, and a third opening provided in the second valve chamber. Thus, flow rate fluctuations are reduced even when the pressure on the ejection side or the suction side of the device fluctuates due to changes in atmospheric conditions. | 10-03-2013 |
| 20150059878 | PRESSURE REGULATING VALVE - A pressure regulating valve includes a device body and an actuator. The device body includes a valve seat member, a valve, which is capable of closing the first opening of the valve seat member, an urging member, which urges the valve toward the valve seat member, a piston arranged opposite to the valve across the valve seat member, an actuator, which adjusts the position of the piston, and a protrusion provided on at least one of the piston and the valve. When the tip end of the protrusion comes into contact with the piston or the valve, the second opening of the second fluid passage is closed. When the tip end of the protrusion is not in contact with any of the piston and the valve and the second opening is opened, the second fluid passage is in communication with the pressure regulation chamber. | 03-05-2015 |
| 20150075649 | PRESSURE REGULATOR | 03-19-2015 |
| 137505150 | Ancillary reactor surface responds to inlet pressure | 3 |
| 20110290346 | Fluid pressure control device - A fluid pressure regulating apparatus is provided. The apparatus includes a chamber having a first bore diameter, a second bore diameter, a fluid inlet for receiving fluid at an unregulated pressure, and a fluid outlet for discharging fluid at a regulated pressure. A shuttle assembly is located in the chamber, the shuttle assembly including a valve that is in fluid communication with both the fluid inlet and the fluid outlet, and a first sealing member located at an upper portion of the shuttle assembly and a second sealing member located at a lower portion of the shuttle assembly. An unregulated pressure zone communicates with the fluid inlet, a regulated pressure zone communicates with the fluid outlet and a fluid pressure control zone communicates with a portion of the shuttle assembly, the fluid pressure control zone controlling the regulated pressure at the fluid outlet. | 12-01-2011 |
| 20120000552 | Fluid pressure control device - A fluid pressure regulating apparatus is provided. The apparatus includes a chamber having a first bore diameter, a second bore diameter, a fluid inlet for receiving fluid at an unregulated pressure, and a fluid outlet for discharging fluid at a regulated pressure. A shuttle assembly is located in the chamber, the shuttle assembly including a valve that is in fluid communication with both the fluid inlet and the fluid outlet, and a first sealing member located at an upper portion of the shuttle assembly and a second sealing member located at a lower portion of the shuttle assembly. An unregulated pressure zone communicates with the fluid inlet, a regulated pressure zone communicates with the fluid outlet and a fluid pressure control zone communicates with a portion of the shuttle assembly, the fluid pressure control zone controlling the regulated pressure at the fluid outlet. | 01-05-2012 |
| 20180024576 | Stable Pressure Regulator Apparatus | 01-25-2018 |
| 137505160 | Liquid transfer | 1 |
| 20090277518 | Emergency motor vehicle reserve fuel system - An emergency fuel supply system comprising a main fuel tank having a separate internal fuel reservoir which automatically refills itself with a reserve quantity of fresh fuel each time the main tank of the vehicle is refilled. A remotely controlled electric fuel pump or dump valve permits the vehicle operator to selectively jettison the reserve fuel into the main tank, either to provide a reserve supply in an emergency when the fuel in the main tank is depleted, or to empty the reserve tank of possibly stale fuel so that it may be refilled the next time the main tank is refilled. | 11-12-2009 |
