Abrégé
Provided is a safety valve that is capable of minimizing creep of a fusible alloy even if a member that closes a flow path directly presses the fusible alloy. In the present invention, a fusible alloy 6 is placed between a pressing cap 4 and a closing member 3 that blocks the flow of a fluid flowing from a discharge passage 91 of a fluid device 9, an accumulating portion 8 where the molten fusible alloy 6 accumulates is formed in at least one of the closing member 3 and the pressing cap 4, and two porous plates 5A, 5B of which perforated positions do not overlap are provided between the accumulating portion 8 and the fusible alloy 6.

Abrégé
The pressure reduction valve includes: a cylindrical portion, a piston and a spring. The cylindrical portion includes an inlet communicating with the primary side flow path and an outlet communicating with the secondary side flow path. The piston fitted into the cylindrical portion is slidable along an axis direction of the cylindrical portion within the cylindrical portion, and defines, within the cylindrical portion, a space communicating with the inlet and the outlet. The spring applies, to the piston, a force acting toward the space. The outlet is displaced in one direction from the center of the piston when seen in the axis direction. The force applied to the piston by the spring is distributed so as to deviate from the center of the piston to the side of the outlet.

Abrégé
Provided is a throttle valve in which gaskets respectively disposed on both ends of a filter are not squashed during operation. The throttle valve includes a throttle valve element; a support member that supports the throttle valve element, the support member including a valve element support portion, and a shaft portion that is connected to the valve element support portion, the shaft portion having a gas passage and an inlet port; a mounting member that mounts the support member in a throttle valve flow passage; a filter disposed on an outer peripheral surface of the shaft portion to cover the inlet port, in a space whose axial length is defined by the shaft portion and the mounting member; and gaskets that are respectively disposed between one axial end of the filter and the mounting member and between the other axial end of the filter and the shaft portion.

Abrégé
A valve element (12) of a pressure reducing valve includes a taper portion (23) seated on an inner periphery of a valve hole (31). The valve hole (31) includes a first area (33), a second area (34) and a third area (35) in order from an upstream side. The first area (33) is provided such that, when the valve element (12) is open, the height of a passage defined between the first area (33) and the taper portion (23) gradually reduces toward a downstream side. The second area (34) is provided such that the height of a passage defined between the second area (34) and the taper portion (23) is constant when the valve element (12) is open and the entire second area (34) contacts the taper portion (23) when the valve element (12) is closed. The third area (35) is provided such that, when the valve element (12) is open, the height of a passage defined between the third area (35) and the taper portion (23) gradually increases toward the downstream side.

Abrégé
A valve device includes a body (11), a solenoid valve (12) accommodated in an accommodation hole (23) of the body (11), and a joint member (110) fixed to the body (11). The solenoid valve (12) includes: a sleeve (41) having a tubular shape and fitted in the accommodation hole (23), and including an introduction passage (66) and a delivery passage (68); and a valve element (71) configured to open and close the passages (66, 68). A U-seal (57) is disposed between an outer wall surface of the sleeve (41) and an inner wall surface of the accommodation hole (23). The body (11) has an attachment hole (80) that is located downstream of the delivery passage (68) of the sleeve (41) and opens on an outer surface of the body (11). The joint member (110) including a backflow reduction valve (122) is fixed to the attachment hole (80).

Abrégé
A valve device includes a body in which a gas flow passage is provided; and a check valve provided in the gas flow passage, the check valve including a poppet and a valve seat. The poppet excluding a block portion is in a form of a hollow shaft, the block portion being located at a distal end of the poppet and having a taper shape, and the poppet has at least one side hole that provides communication between an inside and an outside of a portion of the poppet, the portion being in the form of the hollow shaft. The at least one side hole extends obliquely with respect to a central axis line of the poppet such that the at least one side hole extends along a gas flow direction inclined with respect to a direction in which the poppet moves when the check valve opens.
