Pressure response of high pressure fluid valving, apparatus and methods therefor
Disclosed is a system, method and apparatus operating on a high-pressure working fluid with high efficiency. The device has a reservoir of high-pressure working fluid. A fluid connection supplies the high-pressure working fluid at a controlled working pressure to a dose chamber to contain a volume of the high-pressure working fluid. A dose valve, biased to close, and able to be triggered open, is present between the dose chamber and a working chamber. A charge of the high pressure working fluid can be released from the dose chamber via the dose valve at a first end of the working chamber, to undergo a first expansion in the working chamber and do work therein to or towards a second end of the working chamber distal from the first end. The dose valve closes again before a pressure front of the charge in the working chamber has travelled less than or equal to halfway between the first end and the second end. This allows a second expansion of the charge to continue doing work. When the work is complete, the working chamber pressure is less than or equal to half the working pressure.
Disclosed is a pressure relief valve with inlet and outlet ports, to hold pressure from outlet until a set pressure is achieved at the inlet. The valve has a valve member located between the inlet and outlet ports, movable between an open position to allow a fluid flow between the ports, and closed position to prevent fluid flow. Inlet pressure acts on the valve member to increase its closing force. Provided is a movable sensing spindle in fluid communication with the inlet pressure and a reference pressure, the sensing spindle having a first position, and a second position. Increased pressure difference between the inlet pressure and reference toward the set pressure moves the sensing spindle to eventually acts on the valve member to move it away from it's sealing position and thus provide an opening for fluid to flow from the inlet to the outlet.

A device for filling a small portable pressure vessel from a larger pressure vessel with a compressed fluid such as carbon dioxide. The device comprises an inlet adapted to receive fluid from a pressurized source, and an outlet adapted to connect to a pressure vessel. Between the inlet and the outlet there is a fill valve and a vent valve and at least one cam shaft configured to rotate and operate the valves.
A compressible fluid powered device includes a dose chamber. An inlet supplies pressurized fluid to the dose chamber. An outlet for releases pressurized fluid from the dose chamber. A moveable divider divides the dose chamber into a primary space and a secondary space, movement of the divider expanding one space at the expense of the other. At least one flow pathway from one space to the other, which collectively allow gas to flow in both directions past the divider and pressure to equalize across the divider, the flow pathway being much more limited than the outlet.
A gas powered device includes a vaporisation system. The vaporisation system includes a conduit connected at one end, or configured to connect at one end, to a regulator for a high pressure fluid source. The other end of the conduit supplies an operating mechanism of the device The path of the conduit is such that a substantial length of the conduit is adjacent the operating mechanism.
A device includes an actuation system with a dose chamber including an inlet for high pressure fluid. A working chamber extends away from the dose chamber. An annular wall separates a portion of the working chamber from the dose chamber such that the dose chamber encompasses the portion of the working chamber. In use an item to be driven along the working chamber is at least partially within the surrounded portion of the working chamber with the item at one end of its travel in the working chamber. A valve mechanism selectively allows high pressure fluid from the dose chamber to flow into the piston chamber.
A compressible fluid powered device includes a dose chamber. An inlet supplies pressurised fluid to the dose chamber. An outlet for releases pressurised fluid from the dose chamber. A moveable divider divides the dose chamber into a primary space and a secondary space, movement of the divider expanding one space at the expense of the other. At least one flow pathway from one space to the other, which collectively allow gas to flow in both directions past the divider and pressure to equalise across the divider, the flow pathway being much more limited than the outlet.
