    Abstract: The invention relates to a micro valve normally in a closed position, comprising a membrane (80), an activating device (100) for controlling the deformation of the membrane (80) and a valve seal (180) which is deformed by the controllable deformation of the membrane (80). The valve seal (180) is situated at least partially opposite the membrane (80) and is arranged in a first position in the normally closed position of the valve, along a sealing lip (130) disposed between the valve seal (180) and the membrane. The sealing lip (130) is so arranged that an outlet of the valve, which is fluidly connected to an interrupted section of the sealing lip (130), is fluidically sealed in relation to an inlet channel (170) which boarders on the valve seal (180). The valve seal can also be deformed in a second position in order to enable a fluidic connection between the outlet (140) and the inlet channel (170) when the valve is in an open position.

    Abstract: The invention relates to a method for producing a pump body comprising an inlet having an inlet valve (106) and an outlet having an outlet valve (108). According to said method, the first step is for a first main surface each of a first and second semi-conductor wafer (200) to be structured so as to establish a valve flap structure (202) for the inlet valve and a valve seat structure (204) for the outlet valve in the first wafer as well as a valve flap structure for the outlet valve and a valve seat structure for the inlet valve in the second wafer. Thereafter, for each wafer, one trough-shaped structure for a valve flap (206; 216) and one trough-shaped structure for a valve opening (208; 218) is embodied in a predetermined relationship to the valve flap structures and the valve seat structures in the respective second main surfaces of the first and second semi-conductor wafer. The first main surfaces of the first and second semi-conductor wafer are connected in such a way that each valve flap structure is positioned in a predetermined relationship to a valve seat structure. Lastly, the second main surfaces of the first and second semi-conductor wafers are etched at least in the area of the trough-shaped structure for a valve flap and the trough-shaped structure for a valve opening so as to release the valve flaps and open the valve seats.
