Abstract: A bleed valve which is intended for the fuel tank of a vehicle has a housing, a floating body disposed in such a manner as to be able to move in the longitudinal direction. A rim of an outlet orifice forms a valve seat for a sealing element which is supported by a support disc, wherein the support disc is articulated in a cardanic manner on the floating body. The sealing element is disposed in such a manner as to be able to move according to the movement of the floating body between a position which closes the outlet orifice and a position which opens same, wherein as a result of the said articulation of the support disc on the floating body positional changes, e.g. inclined positions, which are caused by the drive operation of the vehicle do not impair the sealing function.

Abstract: A bleed valve which is intended for the fuel tank of a vehicle consists of a housing (1) which on the topside comprises an outlet orifice (6) and an orifice (4) which is intended for connection to the head space of a tank, a floating body (3) which is supported by means of a spring on the base (1?) of the housing (1) and is disposed in such a manner as to be able to move in the longitudinal direction thereof. The rim (19) of the outlet orifice (6) forms a valve seat for a sealing element which is supported by a support disc (12), wherein the support disc (12) is articulated in a cardanic manner on the floating body (3). The sealing element is disposed in such a manner as to be able to move according to the movement of the floating body (3) between a position which closes the outlet orifice (6) and a position which opens same, wherein as a result of the said articulation of the support disc (12) on the floating body (3) positional changes, e.g.

Abstract: A fuel tank protection valve is provided. The valve consists an all-metal diaphragm suitable for operating at low temperatures. The valve includes a tank duct connected to the fuel tank and a second duct connected to a filter. A sealing device is connected to the diaphragm adapted to open and close a passage between the tank duct and the second duct. The valve further includes a one-way, mushroom type valve to allow gas flow from the filter to the gas tank. A clamp cover with air passage openings is included to allow equalization of the pressure between the ambient air and the air pressure within the cover space.
