ABSTRACT:
The present invention teaches a valve mechanism with constraint guide means. Both opening and closing of any valve working according to the principle of the invention is achieved by moving a central plate with respect to one or two plates for blocking flow through the valve. The constraint guide means according to preferred embodiments of the invention consist of grooves in the plates which cooperate with middle plate. As the grooves are inclined with respect to the direction of movement of the middle plate, a movement between these plates and the middle plate will cause opening or closing of the valve.
