| 摘要 |
The invention relates to a device (1) with a nonreturn valve, comprising an inner chamber (11) communicating with an inlet conduit (3) and an outlet channel (5). The device (1) consists of two parts (2, 4), the joint plane (7) of which passes through the inner chamber (11). An elastic membrane (18) is fixed between the junction flanks (14, 15) of the two parts (2, 4) and bears against an annular flange (23) surrounding the orifice (12) of the inlet conduit (3) in the inner chamber (11). The membrane (18) is tensioned by an annular rib (24) provided on the wall (10) of the outlet body (4) delimiting the inner chamber (11). <IMAGE>
