<P>PROBLEM TO BE SOLVED: To provide an integrated valve assembly with a main body. <P>SOLUTION: The integrated valve assembly is equipped with an inner gas passage for sending gas to a gap between a gas inlet and a gas outlet, gas inflation means (10, 12) equipped in the inner gas passage between the gas inlet and the gas outlet, and an engagement valve (9) with a rotary actuator (18) which is used for controlling discharge of gas and operated by a user. This assembly further has an obstruction means (17) to act on the rotary actuator (18) of the engagement valve (9) so as to usually prevent the actuator (18) from being rotated in either direction. The subject portable walking type device is equipped with a compressed oxygen cylinder (1) provided with such an integrated valve assembly, a protective surrounding body arbitrarily protecting the assembly (2), and a demand valve connected to an oxygen therapy nose clip or a flow meter or an arbitrary other similar device. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
