Abstract

A gas pressure accumulating and supplying device for use in model guns, which comprises a pressure accumulating chamber provided in a case member, a gas injecting opening provided on a bottom portion of the case member, a gas introducing structure extending from the gas injecting opening into the pressure accumulating chamber, a gas discharging passage extending from the pressure accumulating chamber, and a control valve structure provided in the gas discharging passage for controlling supply of gas pressure from the pressure accumulating chamber. The pressure accumulating chamber is provided therein with a partition member for partitioning the pressure accumulating chamber into a main chamber into which liquefied gas is injected through the gas introducing structure from the gas injecting opening and a subchamber positioned between the main chamber and the gas discharging passage and a gas passage forming portion extending from the partition member into the main chamber for forming a gas passage connecting the main chamber with the subchamber and having an end portion reaching a position the gas introducing structure.
