Abstract

The valve is fitted to the outlet valve (2) of a liquified propane storage cylinder (3). A spring (6) presses a piston (5) into the outlet passage from the cylinder. An inlet (7) on the side of the piston opposite the spring allows external hydraulic, gas or pneumatic control to raise the piston and open the valve. An outlet (8) to atmosphere is provided on the spring side of the piston.

Description

Le dessin annexé illustre l'invention La figure 1 représente en coupe, une variante de ce dispositif. The accompanying drawing illustrates the invention. FIG. 1 represents in section, a variant of this device.

La pression de libération du gaz propane liquéfié, qui sort de sa réserve importante, étant faible, est retenue par le -ressort de forte puissance. The release pressure of the liquefied propane gas, which leaves its large reserve, being low, is retained by the high-power spring.

Par l'assistance hydraulique, il est possible de libérer ce combustible qui va servir au désherbage thermique des plantes adventices dans les cultures agricoles, toutes corporations confondues.By hydraulic assistance, it is possible to release this fuel which will be used for thermal weeding of weeds in agricultural crops, all corporations combined.
