Abstract: A valve structure for a fluid pressure device. A valve element for constituting a pressure reducing valve is provided with a first housing which is interconnected with a stem, a second housing which is provided on the outer peripheral side of the first housing, and packing which is provided between the first housing and the second housing. The packing is mounted and sandwiched between a tapered section of the first housing and an outer wall section of the second housing, and thereby the packing is affixed. A first tube section of the first housing is inserted into a second tube section of the second housing, and the first housing and the second housing are affixed integrally to each other by, for example, welding or adhesion.

Abstract: A valve structure for a fluid pressure device. A valve element (50) for constituting a pressure reducing valve (10) is provided with a first housing (58) which is interconnected with a stem (48), a second housing (60) which is provided on the outer peripheral side of the first housing (58), and packing (62) which is provided between the first housing (58) and the second housing (60). The packing (62) is mounted and sandwiched between a tapered section (66) of the first housing (58) and an outer wall section (74) of the second housing (60), and thereby the packing (62) is affixed. A first tube section (64) of the first housing (58) is inserted into a second tube section (70) of the second housing (60), and the first housing (58) and the second housing (60) are affixed integrally to each other by, for example, welding or adhesion.

Abstract: The present invention relates to a pressure reducing apparatus. A diaphragm made from an elastic material is provided in the interior of a body. The diaphragm includes a main body portion having a seat member that is capable of being seated on an inner tubular member of the body, a retaining portion disposed on an outer peripheral side of the main body portion and which is slidably displaceable with respect to the inner tubular member, and a skirt that is retained on a flange of the body. Additionally, by flexing of the skirt by means of an elastic force of a spring, the seat member thereof separates away from the inner tubular member.
