Title: Check valve
Inventor: MIKAMI ISAO
IPC: F16K15/14
Filed: 2009-06-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a thin film check valve which can be attached to inside of an intake pipe and an exhaust pipe of a check valve pump when air in an inner tip portion of a shoe is taken in/out, in a check valve-attached pipe in which the flexible thin film check valve is attached to inside of the cylindrical pipe.  <P>SOLUTION: An approximately triangular roll-shaped flexible thin film is attached to inside of the pipe and the thin film serves as a check valve. When gas is made to flow in from the arrow 6 direction, the roll-shaped thin film check valve 4 becomes a state attached to the inner wall of the cylinder along a flow of the gas. The gas 6 made to flow in passes through the arrow 7 direction while flowing on the surface of the thin film without resistance. When gas is made to flow in from the arrow 8 direction reverse to the arrow 7 direction, the thin film check valve 4 is inverted to the direction of the dotted line arrow 9 due to the pressure of the gas, the thin film check valve 4 is expanded inside the pipe to close it, so as to exhibit thin film check valve effects.  <P>COPYRIGHT: (C)2010,JPO&INPIT
