A valve device includes a body, a joint, a check valve, a valve seat fixation member having an outer peripheral surface on which an external thread is provided, and a sealing member. The body has an attachment hole that attaches the joint and the valve seat fixation member from an outside of the body in a sequence of the joint and the valve seat fixation member, and that has an inner peripheral surface in which an internal thread screwed to the external thread of the valve seat fixation member is provided. The sealing member is provided between the joint and the valve seat fixation member. An outer peripheral edge of the sealing member is located radially inward of a screwed region of the internal thread and the external thread.

Valve device

A solenoid valve includes a coil, a valve element receiving portion, a valve element placed inside of the valve element receiving portion, and a valve portion configured to open and close a gas flow path accompanied with move of the valve element. Either a surface of the valve element opposed to the valve element receiving portion or a surface of the valve element receiving portion opposed to the valve element has a first groove that is extended in an axial direction and a second groove that is arranged to intersect with the first groove and to be extended in a circumferential direction. The first groove is formed to be extended at least from the second groove toward a valve portion-side.

Solenoid valve

A valve device for a gas tank, includes a body and a check valve provided in an injection passage to inject gas into the gas tank. The check valve includes a valve seat, a case fixed in the injection passage while a space is provided between an inner peripheral surface of the injection passage and the case to enable gas to flow through the space, and a valve element accommodated in the case. The case includes a cylindrical portion, and is configured such that the bottom of the cylindrical portion, provided at an opposite side to the valve seat, defines a range where the valve element is axially movable. The valve element includes a head portion that can block a valve hole of the valve seat, and a sliding portion formed to be axially movable with respect to the cylindrical portion.

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.

A 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 that is 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.

Throttle valve

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

A valve apparatus includes a body with a supply passage for gas and a solenoid valve housed in the body. The solenoid valve includes a tubular sleeve internally having a flow passage leading to the supply passage, and a valve element and a valve seat that open and close the flow passage. The solenoid valve includes a driving portion that opens and closes the valve element. A seal member is disposed between an outer wall of the sleeve and an inner wall of the body. A tip of the sleeve on a downstream side of the valve element is exposed from the body.

Valve apparatus

The valve unit includes: a body having a charging passage; a supply-side joint that connects a supply pipe; and a check valve that is disposed in the gas passage, and that inhibits gas from being discharged from the gas tank to the outside of the body. The check valve includes a check valve seat, a check valve element that comes into contact with or moves away from the check valve seat, and a positioning member that fixes the position of the check valve seat in the charging passage. The body has a fitting hole which is communicated with the charging passage and in which the supply-side joint and the positioning member are fitted. The positioning member is fitted in a second fitting hole so as to fix the position of the check valve seat even when the supply-side joint has not been fitted in a first fitting hole.
