Abstract: An air pump is configured as a reciprocating compressor. On a fuel tank, there is fitted a cylinder of the air pump, in which an axially displaceable piston rod, having a handle and a piston, is coaxially disposed. The piston divides the interior of the cylinder into two chambers. The lower one of these chambers, lying closer to the fuel tank, communicates with the fuel tank via a first one-way valve, which permits only the entry of air into the fuel tank. The upper one of these chambers, lying farther from the fuel tank, communicates unchecked with the atmosphere. The one-way sealing of the piston against the cylinder allows the passage of air past the piston only in the direction from the upper chamber to the lower chamber. The piston rod is provided with a coaxial duct and a second one-way valve which is opposed to the first. The two chambers are able to intercommunicate via the coaxial duct and the second one-way valve, which, from a predetermined pressure, allows air to escape to the atmosphere.

Abstract: The present invention is a toy water gun which is operated by selectively releasing water from a water reservoir that is pressurized with air. The gun has amanually operated air pump which pressurizes a water reservoir and consequently pressurizes any water therein. The pressurized water has an avenue of release that is regulated by a trigger mechanism. When no force is applied to the trigger, the pressurized water is held at bay with no means of release. When force is applied to the trigger, water is released from the pressurized reservoir and is channeled through a narrow nozzle. The escape of the pressurized water through the narrow nozzle creates a stream of propelled water that lastas as long as the trigger is engaged or until the pressure on the water in the reservoir equals the ambient air pressure. Water is added to the present invention via at least one fill opening on the water reservoir. The reservoir itself is non-detachable from the gun housing.

Abstract: A gas storage and dispensing system is described for the substantially reversible storage of a gas. The system comprises a material (4) having open voids occupied by a liquid. The liquid is a solvent of the gas and such occupation of the open voids by the liquid, with the gas dissolved therein, forms a reversible sorption gas storage system. The system tends to sorb increasing quantities of gas in increasing ambient gas pressure and desorb previously sorbed gas with decreases in ambient gas pressure. The system may be used in a pressure pack dispenser for dispensing a product (11) under pressure of a propellent gas, where the system provides the source of pressurised propellent gas.

The intermediate means has a flexible and collapsible tube extending into the accumulator from the bowels of the accumulator and a straight rigid tube having a free end. The free end of the rigid tube always lies at the lowest level in the accumulator regardless of the altitude of the injector so as to dip into any liquid in the accumulator.

Abstract: A toy water gun has a pump/valve subassembly in which a flange plate is affixed to the outlet end of the cylinder member of an air pump. An integral tubular boss extends from the flange plate externally of the cylinder member outlet, the boss serving as the valve body of a discharge control valve. An annular gasket on the perimeter of the flange plate laterally outwardly of the cylinder member and the valve body forms a seal with the neck of a water reservoir, whereby the air pump outlet to the water reservoir and the inlet to the discharge valve communicate directly with the reservoir. A trigger operates the normally closed discharge control valve, and water under pressure is expelled from the reservoir through a discharge tube and nozzle when the trigger is pulled. A pressure-relief valve on the air pump prevents the pump from pressurizing the air pumped into the reservoir to a pressure above a predetermined value.
