During the compression stroke, the piston pushes oil from the cylinder into the diaphragm head where it flows through the perforated plate to the back side of the diaphragm. T he diaphragm is thus forced to bend into the concave diaphragm head cover surface. As the piston moves back, it pulls the diaphragm against the surface of the perforated plate which is also concave. So the oscillation frequency of the diaphragm corresponds to the compressor speed.
