PCT No. PCT/CH79/00052 Sec. 371 Date Dec. 6, 1979 Sec. 102(e) Date Nov. 15, 1979 PCT Filed Apr. 5, 1979 PCT Pub. No. WO79/00896 PCT Pub. Date Nov. 15, 1979.The invention concerns a valve with servo-command, consisting of a seat (5) and a poppet valve (6) mounted in a valve body (1). Movements of the poppet valve (6) are prompted by the pressure prevailing in the control chamber (7). The intake of fluid under pressure in this chamber (7) takes place through an intake conduit (22) which opens across from the upstream edge of the seat (5) in relation to the direction of flow of the fluid, in proximity to the smallest cross section for passage of the fluid for all the possible positions of the poppet valve in relation to the seat (5). |
