Abstract
A pressure surface forming a boundary of a plenum has an orifice therein through which the flow is channeled. An elastomeric body having a surface with curvature different than that of the pressure surface is squeezed to varying degrees against the pressure surface causing the elastomeric body to contact the pressure surface over an area which increases with increasing squeeze. The orifice is positioned and sized to be wholly within the maximum contact area of the elastomeric body with the pressure surface and to extend outside of the minimum area. At intermediate degrees of squeezing the elastomeric body exposes a finely controlled opening for flow through the orifice.
