Pressure relief valve with permanent magnets

A pressure relief valve with excellent properties and feasible in a simple structure is presented here. The structure is flat and is optimized for the usage in the fluidic printed circuit board technology. The here presented pressure relief valve is alike conventional solutions with an orifice closed with a sealing element. As a force generating element permanent magnets are proposed here. This leads to excellent opening and closing behavior, self alignment and to a very simple structure. The here described pressure relief valve works in a range of 300 mBar, but a wide range of set pressures can be achieved by the variation of design properties.
