Title:
CHANNEL COUPLING IN BLOW BACK TYPE GAS GUN
Document Type and Number:
Japanese Patent JP3200597
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make smooth the blow back operation of a slider by providing the inlet of a movable side channel such that it can be retracted and reset with respect to the outlet of a fixed side gas channel and providing means surrounding the inlet and outlet when they are coupled while facing each other thereby preventing leakage of gas.
SOLUTION: An inlet 17 is provided oppositely to the outlet 16 of a gas channel at the time of coupling. The outlet 16 is opened to the upper surface of a raised part 21 and an inlet 17 is provided in the lower surface of a movable member built in a slider. The movable member serves as a cylinder 23 at the intermediate and subsequent part thereof. The inlet 17 is projected downward to be fitted in the periphery of the outlet 16. The inlet 17 and the outlet 16 are coupled tightly. A substantially U-shaped wall 25 surrounds the raised part 21 of the outlet 16 on the rear and left and right sides thereof to block gas leaking outward.
