    CPC classification number: F16L41/03

    Abstract: The present invention provides a connecting structure for piping members that are easy to connect and ensure prevention of liquid leakage even if sealing performance deteriorates due to weakened crimping force of the connected portion as a result from creep caused by changes in fluid pressure and temperature over prolonged periods and connected parts are susceptible to separation owing to looseness occurring in securing members. The structure is characterized in that a first piping member having a channel therein, the first piping member having at least one of a first joint surface on the periphery of which at least one of a first opening in communication with the channel and with a first annular groove is provided and a second piping member having a channel therein, the second piping member having at least one of a second joint surface on the periphery of which at least one of a second opening in communication with the channel and with a second annular groove is provided are connected with a thinner-walled sleeve with flanges on both ends on the periphery of which elastic bodies are fitted and press-inserted into the first and second annular grooves.

    Abstract: There is provided a shutter opening/closing apparatus which automatically performs shutter opening or closing in accordance with an insertion of a cartridge and does not give an influence, such as abnormal noise or backlash, to loading and unloading of a cartridge. The shutter opening/closing apparatus includes a follower member 18 configured to be engaged, at an opening 11 of the cartridge 10, with a portion of a drive member 13 driven in the cartridge 10 for opening or closing a shutter 15 provided for the cartridge, and a cam mechanism 7, 7a limiting a movement of the follower member 18 so as to avoid contact of the follower member 18 to the opening 11 of the cartidge 10 at a time when the engagement between the follower member 18 and the portion of the drive member 13 is released.

    Abstract: A valve (100) includes a body (1) having a valve seat (10) formed therein, a bonnet (2), a diaphragm (3) supporting a valve element (18) abutting against and moving away from the valve seat (10), and an elastic member such as an O-ring (5). The body (1) is formed with an annular groove (13) extending around the valve seat (10), and the diaphragm (3) is provided at the peripheral edge (20) with an annular engagement part (21) formed to have an approximate L-shape in cross-section. The annular engagement part (21) is inserted into the annular groove (13) in a tight state by the elastic member disposed between the bonnet (2) and the annular engagement part (21) of the diaphragm (3).
