Abstract
A pump with a priming circuit containing a valve having a seating with an orifice and an obturator mounted so as to be able to be applied onto the seating in front of the orifice, where the obturator is a resilient blade embedded on one side to the seating. The flexibility of the blade increases from the embedded side to the other. An L-shaped member protrudes from an outer curvilinear wall of a priming element fixed onto the pump. The L-shaped member allows for the seating to be slide into a groove space. The obturator has two holes so that the obturator can be embedded onto the seat by mating with two projections from the seating surface.
Claims8
A pump with a priming circuit containing a valve having a seating with an orifice and an obturator mounted so as to be able to be applied onto the seating in front of said orifice, said obturator being a resilient to said seating on one side, of said seating, the flexibility of the resilient blade increasing from the embedded side to an opposite side wherein an L-shaped member protrudes outwardly from an outer curvilinear wall of a priming element fixed onto the body of the pump, the L-shaped member defines a groove space between a distal leg of the L-shaped element and the priming element, and the seating is slidably received in the groove space.
