Title:
逆止弁、充填機能付き圧力ゲージ
Document Type and Number:
Japanese Patent JP7345171
Kind Code:
B2
Abstract:
To enable even a physically weak operator to easily perform supply operation, in a pressure gauge with a filling function that moves a valve to an open position by manual operation against elastic force energizing to a closed position and supplies compressed air to a tire.SOLUTION: A pressure gauge 1 includes a main valve 101v that is pressed by air pressure when the air pressure transmitted from a tire side is a predetermined pressure value or more, and is retracted to an open position permitting the movement of air on the tire side and a compressed air supply source side, a pressure measuring portion 102 that measures the air pressure of the tire transmitted from the tire side, a check valve 101z that is provided between the main valve and the compressed air supply source, permits an air flow from the compressed air supply source toward the main valve, and cuts off a flow in the opposite direction, and a main valve opening/closing mechanism 104 that receives the operation force of an operator, moves the main value to an open position against elastic force energizing the main valve toward a closed position, and permits an air flow from the main valve toward the tire. A predetermined pressure value is lower than an upper limit value of a measurable pressure range set in the pressure measuring portion.SELECTED DRAWING: Figure 2
