Patent number: 6837267Abstract: A cartridge insert for insertion in a fluid line is provided having a cartridge housing within which is located at least one backflow inhibitor and downstream at least one flow regulator. The backflow inhibitor has a closing element, which, in a closed position thereof, lies tightly sealed on a valve seat of the cartridge housing and which may be displaced from the closed position against a return force into an open position. A downstream guide pin projects from the closing element, and extends into a guide opening of a central regulator core of the flow regulator, and the flow regulator is formed from a regulator element made from an elastic material that surrounds the regulator core, which rests on an annular shoulder and defines a control gap, which changes with pressure between the above and an opposing enclosing wall.Type: GrantFiled: March 14, 2002Date of Patent: January 4, 2005Assignee: Neoperl GmbHInventors: Christoph Weis, Uwe Zoller

Patent number: 6779554Abstract: The invention relates to a backflow preventing check valve (1) comprising a housing (2) in which a closing member (3) is arranged. The closing member is moveable between a closed position and an open position and is disposed on a valve seat with a sealing area in the closed position. A pressure-compensation device is provided for when the backflow preventing check valve is closed and a volume of fluid is sealed off on the outflow side. In order to counteract an undesireable high pressure load when the check valve is closed, the outflow area defined by the closing body (3) in a closed position is joined to at least one pressure compensation chamber (6) whose receiving volume corresponds approximately to the expansion volume of the sealed-off fluid and which is disposed outside the area which is defined on the outflow side.Type: GrantFiled: September 9, 2003Date of Patent: August 24, 2004Assignee: Dieter Wildfang GmbHInventors: Christoph Weis, Martin Fangmeier
