A combination valve including an electromagnetic shut-off valve and an integrated pipe-break protection includes an inflow and an outflow, between which a first flow path is defined, a sealing surface arranged in the first flow path, a movable sealing body including a main seat and a pilot seat, between which a pilot bore is defined as a second flow path, a closing spring, an armature with a sealing surface and a magnetic coil. The sealing body closes the first flow path in the closed position by abutting the main seat against the sealing surface and closes the second flow path by abutting the sealing surface against the pilot seat. The closing spring presses the sealing surface of the armature against the pilot seat of the sealing body and the main seat of the sealing body against the sealing surface. An opening spring presses the sealing body into the open position.

Combination valve

A pressure control valve for gases and/or liquids comprising a first sealing body and a second sealing body for opening and closing a first flow path and a second flow path, respectively. The first and the second sealing bodies can be installed in an inflow for gases and/or liquids in order to define the first and the second flow paths therein. The first sealing body is guided in an axially movable fashion. The second sealing body is guided in an axially movable fashion within the first sealing body. The first sealing body is movable by a force in the effective direction from an outflow to an inflow from a closing position into an opening position in which the first flow path is opened. The second sealing body is movable by a force in the effective direction from the outflow to the inflow from a closing position into an opening position in which the second flow path is opened.

Pressure regulating valve and pressure regulator

A pressure control for a fuel supply device to supply fuel from a reservoir to a user includes at least two flow paths between a high-pressure chamber and a low-pressure chamber, and an operable closure unit for opening and closing of the at least two flow paths.

Pressure regulators for feeding fuel, and fuel-supplying system comprising a regulating unit that consists of said pressure regulators

An electromagnetic valve for a pressure container and which includes a manual shut-off of the valve, a stop, and an electromagnetic shut-off of the valve with a sealing element, a magnet coil, a tappet, and a spring element. When the magnet coil has been currentlessly switched and deactivated, the tappet pressed against the sealing element by the spring element presses the sealing element onto a second opening so as to suppress a fluidic connection from the pressure container. Also, when the magnet coil is activated, the tappet can be moved away from the sealing element as far as the stop, such that the fluidic connection can be released.

Electromagnetic valve for a pressure container

The present invention relates to an electromagnetic valve for a tank valve of a fuel supply system of a gas fuel motor vehicle, comprising a magnetic coil with an inner guide, and a magnetic armature which can move axially in the inner guide. The magnetic anchor consists of an anchor, a seal element which is arranged between the anchor and a fuel inlet, and a counter pole which abuts the seal element. The present invention also relates to such a tank valve and to a fuel supply system having such an electromagnetic valve.

Electromagnetic valve for a tank valve of a fuel supply system

A pressure vesselfor storing a liquid or gaseous medium, having a core vessel, a support jacketarranged at least partially around the core vessel, an openingarranged on one side of the pressure vessel, and a valve body, arranged at least partially in the opening, for open-loop control and/or closed-loop control of the discharging and/or filling of the pressure vessel. The valve bodyis provided as a single piece in the region of the openingand is arranged between the core vesseland the support jacketin such a way that the valve bodycan be fixed in its position, at least partially, by the core vesseland the support jacket

Pressure vessel for gaseous or liquid media

A pressure container comprising a plastic container core () for storing a fluid under pressure, a support sheath () surrounding the plastic container core (), a connection piece () formed at the plastic container core () and having an opening () for filling in and discharging the fluid from the plastic container core (), a connection body () arranged radially outside the connection piece () and having a bore (), a valve body () having a fluid duct () for conducting the fluid in and out through the opening () in the connection piece (), wherein the valve body () is arranged in the opening () of the connection piece () and in the bore () of the connection body (), wherein the connection body () has at least one radially inside annular groove () and a second seal () is arranged in the at least one radially inside annular groove (), so that the second seal () rests radially outside on the connection piece ().

Pressure container

A tank for cryogenic liquids, which is intended for installation in motor vehicles and which consists of an outer container and of an inner container suspended in the latter in tension or compression struts. In order to take the contrasting requirements in motor vehicles into account in an optimum way, between the outer container and inner container abutments and supporting faces are additionally provided, which can be spaced apart from one another when the vehicle is at a standstill and can be brought to bear when the vehicle is driving. The abutments inside the outer container Co.-operate with supporting faces on the inner container and can be displaced by means of an actuator.
