PRESSURE-REDUCING VALVE FOR SUPPLYING PRESSURIZED GAS INTO BOTTLE PROVIDED WITH CAP

摘要

A pressure-reducing valve for supplying pressurized gas to a bottle provided with a cap, the pressure-reducing valve (1) comprising a body (2) inside which there is a piston part (4) and a spring (7) arranged in such a way that the piston part (4) adjusts the flow of the pressurized gas through the pressure-reducing valve (1) and that the piston part (4) is acted upon on one side by the spring (7) force and on the opposite side by the pressure of the pressurized gas, whereupon the spring (7) force determines the pressure that is output from the pressure-reducing valve (1). The spring (7) force acting on the piston part (4) and the pressure level of the gas that is output form the pressure-reducing valve (1) are regulated by pressing the spring (7) for example with the cap (19) of the bottle (18).
