Claims

[Scope of Claim for Utility Model Registration] (1) An inlet connected to the source air reservoir pipe, an outlet connected to the air supply pipe to the brake pipe, a main passage communicating these inlets and outlets, and parallel to this main passage. a throttle passage connected to the throttle passage, an air supply valve that opens the main passage when the flow rate on the outlet side of the throttle passage is equal to or higher than a set value, and a switch mechanism that detects that the flow rate is equal to or higher than the set value. A brake pipe air supply flow rate detection device in which the above inlet and outlet are connected by a bypass passage. (2) The brake pipe air supply flow rate detection device according to claim 1, wherein the bypass passage has a variable throttle.
