Abstract
A valve assembly having a cylindrical valve chamber with radially directed inlet orifices and with a circular spring leaf which resiliently seals the orifices and which may be deflected by fluid pressure within the inlet orifices to open the orifices. The spring leaf is configured so that it may deflect to open the valve inlet without deviation from its essentially oval shape.
