Abstract: A mobile prepressurized fluid storage tank is disclosed where the compressed air, completely separated from the fluid by a flexible diaphragm, dispenses the fluid under pressure, e.g., into an engine. The prepressurized diaphragm-type fluid storage tank is initially charged with a gas on one side of the diaphragm. A connector on the other end of the tank is connected to the fluid pumping system. Fluid is pumped into the tank until a predetermined pressure is reached and then the fill valve is shut off. A second connection attached to a bottom system connection has a hose. At the end of the hose there is a fluid shut off valve. Dispensing of the fluid takes place through the fluid shut off valve. The prepressurized fluid storage tank is mounted on a frame that contains wheels for mobility.

Abstract: A valve for a pressurized container includes a valve housing having a central bore and a port in the for connection of a nozzle. Preferably, the valve has a unidirectional stepped valve housing. In the housing is a central bore that includes an upper portion, lower portion and a middle portion. The lower portion is narrower than the middle portion which in turn is narrower than the upper portion. The port is provided in the middle portion of said housing to facilitate connection of a nozzle to the valve. The valve has a t-stem with a lower end having a key-way and a cavity for receiving the upper portion of the valve seat. The valve seat provides the primary valve seal when the valve is closed. The upper portion of the valve seat has a geometry for engaging the t-stem to provide a locked assembly.

It has a lower portion that is shaped to provide the primary valve seal in cooperation with the valve housing. The upper portion of the valve seat has a geometry for engaging the t-stem to provide a locked assembly.

Abstract: A protective device for gas cylinders is provided that protects the body of the gas cylinder from damage, is light, does not affect the required heat exchange from the environment to the liquified gas within the gas cylinder and renders the gas cylinder assembly easier to stack for safe storage. The protective device in accordance with the principles of the invention comprises a top part and a bottom part forming a cavity within which the gas cylinder is placed. In accordance with an illustrative embodiment of the invention, the top part and bottom part are both made of synthetic materials and are interconnected during assembling process by a standard functional clipping device. These clippings may be broken in order for the protective device to be removed, allowing visual inspection of the gas cylinder without damaging the gas cylinder in the removal process.

Abstract: A gas-liquid vortex separator-eliminator which is adapted to be connected in a closed liquid circulating system having supply and return lines including a circulating pump connected therein for circulating liquid in the circulating system. The upright main body of the devise has an upper chamber and a lower chamber. The upper chamber and lower chambers are separated by a horizontal wall that has a gas discharge port in the center thereof. The inlet has a longitudinal axis which is generally perpendicular to the vertical axis of the upright main body. The inlet has a short pipe leg connected to the upper portion of lower chamber. The outlet has a longitudinal axis which is generally perpendicular to the vertical axis of the main body and which is generally parallel to the longitudinal axis of the inlet. The outlet is positioned in the lower portion of the chamber.

Abstract: A back flow preventer for preventing contamination of a water supply. The preventer includes check valves which are enclosed in a casing comprised of a body and a single removable cover. The check valves are vertically disposed and spaced laterally from each other. The valves may be removed for servicing when the cover is removed without disturbing other parts of the device. Between the check valves is a relief valve which opens to drain the passage between the check valves when there is a drop in the supply line pressure sufficient to cause actual or potential reverse flow back toward the supply line. The check valves open by movement in opposite directions. Each check valve unit includes a tubular strainer through which all water must pass. The check valve units, while identically dimensioned as to the valve structure, include other parts of unequal dimensions which preclude accidental reversal of the units when being initially assembled or replaced after servicing.
