Abstract

PURPOSE: To provide a pressure-responsive two way valve made of an elastic material with an extremely simple construction dispensing with spring.
CONSTITUTION: When the pressure at a connection port 1a is greater than the specified level in the difference from the pressure at a connection port 1b, a pressure- responsive wall 2d and the first valve portion 2a is pushed upward by the excessive difference, thereby allowing the gas at the connection port 1a to flow to the connection port 2b passing through through a clearance between the first valve portion 2a and the first sheet surface 1c. On the contrary, when the pressure at the connection port 1a is lower than specified level in the difference from the pressure at the connection port 1b, the pressure-responsive wall 2d of the valve 2 and the second valve portion 2b are pushed downward, thereby allowing the gas at the connection port 1b to flow to the connection port 1a through the second valve 2a and a second sheet surface 1d. In this manner, this pressure-responsive two way valve is extremely simple in the construction dispensing with spring and highly responsive.
