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.
