Abstract

Improvements in the valvular systems, to control the fluid flow under pressure going to a fluid motor located in a tubular organ, characterized in that said system comprises: a valve support member movably supported adjacent to an open end of the valve. Tubular organ and having a first surface to close said end and define an area outside said end exposed to said fluid under pressure, said support member also defining a second surface opposite said first surface said first surface area subjected to a first force due to said pressurized fluid tending to force said first surface out of the tubular member, said second surface being subjected to a second force counteracting said first force; an elastic disk fixed to said first support surface internally of at least a part of the periphery of the disk, whereby said disk is movable relative to said first support surface, said support member forcing said disk to hermetic contact with said end of the tubular member due to said second force; and means for relieving at least a portion of said second force to allow said pressurized fluid to move said first support member out of said end while initially maintaining said elastic disc in sealing contact with said end, said elastic disc finally jumping out outside said end when the closure member has been spaced from said tubular member with which it instantaneously opens a large opening toward said end of the tubular member so that said pressurized fluid enters to actuate said fluid motor.
