摘要： A monodirectional intake pressure stabilization structure of pneumatic tool includes a tool main body and a pressure stabilization unit. The pressure stabilization unit is disposed in a first directional intake passage formed in the tool main body for controlling the pressure of the air guided by the first directional intake passage into an air chamber of the tool main body. Accordingly, excessively great intake pressure can be avoided so as to avoid over-torque output of the pneumatic tool. In this case, the pneumatic tool can stably output power within a safety range in accordance with the requirements of actual use. The pressure stabilization unit can be a pressure stabilizer or a pressure relief valve.

摘要： A system for hydraulically managing fluid pressure between selected set points includes a pilot control system operably coupled to a main valve. The pilot control system includes at least one fluid conduit, a variable orifice assembly, and a control pilot valve apparatus. Fluid is passed through a fixed orifice and into a first chamber of the control pilot valve apparatus. Fluid is passed through the variable orifice of the variable orifice assembly and into a second chamber of the control pilot valve apparatus. The main valve is hydraulically opened or closed in response to a pressure differential between the first and second chambers of the control pilot valve apparatus so as to manage fluid pressure downstream of the main valve between the selected upper and lower set points.

摘要： A first stage pressure regulator for a two-stage underwater breathing apparatus, comprises a second movable wall (16, 18) for separating a balance chamber (10) from an ambient exposed chamber (17) . The second movable wall is formed by a disk-shaped piston (16) which is slideably and non sealingly guided along the peripheral walls that delimit the balance chamber (10), and by an elastically deformable diaphragm (18), which overlies the side of the piston (16) facing forward the ambient exposed chamber (17) . The elastically deformable diaphragm (18) forms with said piston (16) a diaphragm type pressure relief valve (20, 318).

摘要： A system and method for controlling fluid pressure downstream a main valve includes associating a variable orifice with the main valve such that the variable orifice opens as the main valve is opened and closes as the main valve is closed. A fluid stream taken from a fluid inlet of the main valve is passed to an inlet of the variable orifice. A fixed orifice is in fluid communication with an outlet of the variable orifice. A pressure differential between the inlet and outlet of a fixed orifice is detected by a control pilot device, which hydraulically opens or closes the main valve in response to the detected fixed orifice pressure differential between low pressure and high pressure set points.

摘要： A pressure regulator having a housing with an inlet port and an outlet port. A plug is located within the housing and dividing the housing into an upper chamber and a lower chamber, with the upper and lower chamber being connected by a vent. The plug includes a fluid path between the inlet port and the bore. A yoke is adapted selectively close the fluid path in the plug. A diaphragm is located in the upper chamber and is connected to the yoke. A biasing member biases the yoke to open the fluid path through the plug. The diaphragm is configured to move the yoke to open the fluid path when pressure in the lower chamber and vented to the upper chamber through the vent is above a predetermined amount. The pressure regulator can also include a second biasing member used to positively close the fluid path through the plug.

摘要： A pressure regulator for supplying water to a poultry watering system or the like includes a control assembly for operating the pressure regulator in a normal or “on” mode, an off mode or a flush or bypass mode. A desired operating pressure is set by loading a diaphragm responsive to output pressure changes. Diaphragm movement is transferred by the control system to a valve member cooperating with an inlet orifice. The control system includes a spring captured in a preloaded state between first and second end members, one connected to the valve member and the other connected to the diaphragm. A knob is rotated from a normal “on” position to an off position and a collar pushes the end members together and pushes the valve member against the orifice. The knob is rotated to a flush or bypass position and the collar pulls the end members together and pulls the valve member away from the orifice. The inlet orifice and an inlet port are parts of a removeably mounted inlet member.
