Abstract

See full text

A moderately high pressure, sliding vane pump is fabricated from low modulus plastic by routing high pressure fluid away from the central pump perimeter and into a bearing gland chamber for discharge porting. Port fittings are push socket connections that are sealed by O-rings and held in place against fluid pressure ejection by a saddle plate that cross-pins to the port boss.
