Claims

[Scope of utility model registration request]

Both casings 1 are arranged between an upper casing 1 having an outer cylinder 2 with an inflow port A provided on the side surface and a lower casing 10 with an outflow port C provided.
, 10 is disposed within the upper casing 1.
A diaphragm 4 whose outer periphery is held in a sandwiched state by a lid member 6 provided at the diaphragm 4 and a closing member 7 provided at the center thereof, and an inner cylinder 3 provided inside the outer cylinder 2. The valve seat 3a for the diaphragm 4 formed at the upper part of
A coil spring 8 is disposed to close the gap between the port A and the reed valve 9, and the diaphragm 4 is moved against the biasing force of the coil spring 8 to close the valve seat. A signal pressure port B for separating from the outer cylinder 2 and the inner cylinder 3 is provided in the lid member 6.
A partition wall 19 is provided in a part of the annular fluid flow path 18 formed between the outer cylinder 2 and the inner cylinder 3 where the partition wall 19 is not provided.
The reed valve with an air control valve is characterized in that when the port A is opened, the fluid flowing in from the port A first flows horizontally along the partition wall 19 and then flows into the inner cylinder 3.
