The rod portion of said rocking lever is at right angles to the diaphragm plan and intended to be received in a recess of a sliding sleeve. The diaphragm rocking lever assembly is linked to an axle passing through the rocking lever and bearing on the valve body. The microvalve may be used in chemical and medical analysis devices.
