Title
(EN) SELF-REGULATING VALVE ASSEMBLY
(FR) SOUPAPE AUTORÉGULATRICE
Abstract
(EN)
A self-regulating valve assembly for a compressed gas gun includes a valve housing and a valve body disposed within the valve housing. The rearward end of the valve body defined an outlet port. The forward end of the valve body defines a gas balance reservoir open to and in communication with the breech of the gun. A valve gas passage is provided between the valve body and the valve housing, the valve gas passage providing communication between the outlet port of the valve body and the gas balance reservoir of the valve body. A slideable valve poppet is disposed within the valve body and includes a sensing end adjacent to and at least partially within the gas balance reservoir, the sensing end having a sensing face adapted to react to gas pressure within the gas balance reservoir. The valve poppet is slideable between a closed position and an open position. A valve spring within the valve body biases the valve poppet toward the closed position. Pressure in the gas balance reservoir exerts a force on the sensing face to urge the valve poppet toward the closed position.

L'invention porte sur une soupape autorégulatrice pour pistolet à air comprimé comportant un corps de soupape disposé dans un logement. L'arrière du corps comporte un orifice d'émission et sa partie frontale comporte un réservoir d'équilibrage des pressions communiquant avec la culasse du pistolet. Un passage d'air reliant le corps de soupape à son logement fait communiquer l'orifice d'émission avec le réservoir d'équilibrage. Un clapet coulissant placé dans le corps de soupape comporte une tête de détection contiguë au réservoir d'équilibrage et en partie à l'intérieur, dont la face de détection réagit à la pression à l'intérieur du réservoir d'équilibrage. Le clapet coulissant peut coulisser entre une position de fermeture et une position d'ouverture, et un ressort placé dans le corps de soupape le rappelle len position de fermeture. La pression à l'intérieur du réservoir d'équilibrage exerce une force sur la face de détection amenant le clapet en position d'ouverture.
