Abstract
PURPOSE: To surely replace a fluid, by providing a passage for conducting the fluid of back pressure to a circumferential space and a passage for conducting the fluid forth, at an enlarged inside diameter of a pipe.
CONSTITUTION: A body A defines a passage 7 consisting of a center hole (a) and a radial hole (b) connected thereto. The passage 7 is located between the front end 1 of the body A and its pressure receiving part 2. The passage 7 extends from a circumferential space at a coupled part 5 to a space in front of the front end 1. The body A also defines another passage 8 consisting of a center hole (c) and a radial hole (d). The passage 8 extends from a circumferential space at another coupled part 6 to a space at the rear end 3 of the body. A conical passage 8a connected to the center hole (c) is defined on the rear side of the rear end 3. The fluid of back pressure is conducted into the circumferential spaces and then conducted forth at the enlarged inside diameter of the pipe as the front end 1 of the body is in contact with the inside surface of the pipe 4.
