摘要:
A fluid transfer system includes a transfer device coupled to a dry break coupler. The transfer device includes a valve assembly moveable between an open and a closed position. The valve assembly includes a main valve and a pilot valve. An actuator controls both the main valve and the pilot valve. A cam plate interconnects the actuator and the valve assembly. The cam plate provides a quick acting shutoff to quickly move the valve assembly to the closed position. A pivotal and rotatable connector couples the transfer device to the dry break coupler. A lock is integrated with the actuator to lock the valve assembly in the closed position.

A simple design of an actuating device for a rapid coupling used for transferring gaseous and/or liquid fluids includes a tubular housing and a slide which is movably mounted relative to the housing and is coupled to a lever mechanism that is provided with at least one pivoted lever laterally mounted on the housing. At least one connecting lever extends to the slide on the pivoted lever, thus also obtaining safe handling.

A fuel hose nozzle for filling a tank having a filler the tank with liquefied petroleum gas has a tubular valve housing extending along an axis and having an outer end, a tubular valve guide axially shiftable in the valve housing between a front position and a rear position and forming an outlet port adjacent the outer end, and a valve in the housing movable between an open position permitting fluid flow into the valve guide toward the outlet end and a closed position preventing such flow. A valve piston in the valve guide and axially fixed in the valve housing is engaged in the front position of the valve guide with the port to block flow through same. A fitting sleeve surrounding and axially shiftable on the valve housing has at the outer end an end fitting complementary to the tank filler neck.

The aim of the invention is to create a simple and reliable locking device for a quick-action connection coupling for transferring gaseous and/or liquid fluids, especially for refuelling vehicles. Said device comprises a hand lever (50) for actuating a valve and a lock which is positioned on the end side thereof and engages with a hand grip (45) in the refuelling position. To this end, an unlocking lever (46) which can be pivoted on the hand grip (45) is mounted adjacent to the end region of the hand lever (50). The unlocking lever (46) comprises at least one, preferably two laterally protruding journals (47), arranged inside the hand grip (45), especially for simple handling.

This invention relates to a method for the preparation and metering of substances, mixtures of substances and/or compounds in general, characterized by bacteriostatic and/or bactericidal activity, using a single pressurized container in which the substances, mixtures of substances and/or compounds in general are mixed with carbon dioxide in the form of vapor, liquid/vapor mixture or supercritical fluid for the purpose of mixing, dissolving, storing and dispensing at constant predetermined doses. The invention also relates to pressure containers suitable for dispensing the substances in accordance with the invention.

A mobile system for dispensing cryogenic liquid to a use point includes a low pressure bulk tank containing a supply of cryogenic liquid and a high pressure sump in communication with the bulk tank so as to receive cryogenic liquid therefrom. A check valve is in circuit between the bulk tank and the sump. A heat exchanger is in communication with the sump and selectively receives and vaporizes a portion of cryogenic liquid from the sump when the sump is full as detected by a liquid level sensor. The resulting vapor is directed to the sump so as to increase the pressure therein. The check valve closes when the pressure building within the sump is initiated. The pressurized cryogenic liquid is dispensed from the sump via a dispensing hose. Operation of the system valves is automated by a controller.

摘要:
An inexpensive fuel gas filler structure for a gas-fueled vehicle enables the connection between a ground line and a ground connection portion of the vehicle before the insertion of a fuel gas filler nozzle into a fuel gas filler receptacle. The fuel gas filler structure for a gas-fueled vehicle comprises a fuel gas filler receptacle to which a fuel gas filler nozzle of an external fuel gas filling station is to be connected, a fuel filler lid which is opened or closed, by a fuel filler lid opener, for selectively covering the fuel gas filler receptacle, a ground connection portion to which a ground line of the fuel gas filling station is to be connected, and a ground connection lid which is opened or closed for selectively covering the ground connection portion, wherein an operating section of the fuel filler lid opener is disposed in a region which is covered by the ground connection lid in a closed state.
