Structural component

A tank neck unit for a vehicle that includes a tank neck operatively connected to a pressure accumulator system of the vehicle and which is configured for a predetermined maximum pressure which is greater than a permissible operating pressure of the pressure accumulator system. A shut-off valve is arranged in a throughflow path between the tank neck and an outlet region of the tank neck unit, the shut-off valve being configured to prevent an increase in pressure of the pressure accumulator system beyond the permissible operating pressure.

Filler neck assembly with stop valve

Shut-off valve for a pressure accumulator vessel for a medium, wherein a valve housing has a valve chamber with an intake opening and an outlet opening facing the pressure accumulator vessel, a movable piston, and at least one spring, wherein the piston has at least one axial connecting channel and is guided in an axially movable manner by at least two sealing elements arranged in the valve chamber, wherein a first effective piston surface of the piston, the first effective piston surface facing an inlet region of the valve chamber, and a sealing body form a valve seat, and wherein, by changing the pressure in an accumulator region of the valve chamber, the accumulator region being adjacent to a second effective piston surface, the piston is axially movable and a passage opening arranged between the intake opening and the outlet opening may be reversibly closed and opened, wherein, in the unpressurized state, the passage opening is kept open by the spring. Pressure accumulator system for a vehicle, comprising at least one pressure accumulator vessel and at least one shut-off valve, which is operatively connected thereto.

Stop valve for pressure storage vessel

A shut-off valve to fill a tank with a gaseous medium. The shut-off valve includes a valve housing, a piston arranged in the valve housing for displacement in an axial direction and having an axially continuous bore, a first end piece having an outlet opening which is fluidically-connected to the axially continuous bore of the piston; and a second end piece having an inlet opening which is fluidically-connected to the axially continuous bore of the piston.

Pressure indicator

A pressure accumulator system, and a method of operating a pressure accumulator system. The method includes operatively connecting a tank neck to at least two pressure accumulator vessels having different admissible operating pressures, in which at least one of the pressure accumulator vessels has an admissible operating pressure lower than a maximum applicable pressure at the tank neck, simultaneously filling via the tank neck the at least two pressure accumulator vessels with a fluid medium, and preventing an inadmissible pressure rise in the pressure accumulator vessels with the lower admissible operating pressure during the simultaneous filling.

Pressure storage system and method to operate pressure storage system

A pressurized storage tank arrangement having at least two pressurized storage tanks, the at least two pressurized storage tanks being configured for connection to one another in a fluid-conducting manner via a connecting device. The at least two pressurized storage tanks are configured for connection to the connecting device in a fluid-conducting manner at a first and a second connecting section.

Pressure accumulator

An operable transmission comprising toothed wheels. In order to operate the transmission with a lubricant and coolant which is environmentally friendly while providing improved heat dissipation and temperature-independent viscosity, the transmission contains a mixture of water and a glycol or similar, in which graphite particles are suspended. The mixture contains 40 to 60 percent per weight of the glycol and 2 to 25 percent by weight of graphite in the form of flaky graphite particles having a grain size of less than 12 micrometers, the remainder being composed of water and other admixtures and/or additives. Also disclosed are the lubricant and coolant as well as a method for starting a transmission operated with the lubricant and coolant.
