Abstract

The valve has a pump body (1) with a membrane. The body has a cylindrical inner wall with at least one intake opening (E) and one ejection opening (A) in the side. The ejection opening contains a membrane formed from a cylindrical flexible membrane body (2). The membrane body has a central moveable non-flexible band. The ends of the body are fastened sealed to the pump body. The membrane body contains a turning roller body (4) with a rotary slide.
