Abrégé
(EN)
The invention relates to a pressure valve (11) comprising a body (12) including at least one admission opening (17) and at least one discharge opening (18, 19) a slide valve (13) sliding in said body(12), said slide valve (13) defining a chamber (24), with the body (12), and comprising a head (23) arranged facing a seat (16) of the admission opening (17), a spring (14) pressing the head (23) of the slide valve (13) against the seat (16), and a lip (31) for applying the head (23) to the seat (16). The head (23) comprises at least one hole (33) bringing the chamber (24) into communication withthe discharge opening (18, 19), each hole (33) being arranged facing the seat (16) and downstream from the lip (31) in relation to the admission opening (17) in order to reduce the pressure in the chamber by a Venturi effect when the slide valve is open.

本发明涉及一种压力阀(11),包括主体(12),所述主体包括至少一个进气开口(17)和至少一个排气开口(18、19),在所述主体(12)中滑动的滑阀(13),所述滑阀(13)与主体(12)一起限定腔(24),并且包括面对所述进气开口(17)的座(16)布置的头部(23),将滑阀(13)的头部(23)压靠在座(16)上的弹簧(14),以及将头部(23)施加到座(16)的唇部(31)。头部(23)包括使腔(24)与排气开口(18、19)连通的至少一个孔(33),每个孔(33)均面对座(16),并相对于进气开口(17)位于唇部(31)的下游,以在滑阀开启时通过文丘里效应降低腔中的压力。
