A pressure chamber, which is a space part between the valve element and the valve seat, is provided on the inlet side of the valve element. The valve element includes a plurality of horizontal holes each opening to the pressure chamber, and a vertical hole bringing the horizontal holes and the outlet side of the valve element into communication with each other.

Pressure reducing valve

A valve device includes a body, a solenoid valve, and a manual valve mounted to the body. The manual valve being configured to open and close the gas flow channel via a manual operation. The gas flow channel includes a first flow channel including the valve-side opening portion, and a second flow channel including the tank-side opening portion, and includes an intersection portion in which a first center axis that is a center axis of the first flow channel and a second center axis that is a center axis of the second flow channel intersect with each other. A center axis of the solenoid valve coincides with an extension line of the first center axis and a center axis of the manual valve coincides with an extension line of the second center axis.

Valve device

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.

A valve device includes a body having a gas flow path. When the gas is charged, the first flow path is located upstream of the intersecting portion, and the second flow path is located downstream of the intersecting portion. The gas flow path has a check valve mechanism and a drive mechanism. The check valve mechanism opens a valve when the gas is charged and closes the valve when the gas charge is completed, and the drive mechanism opens the valve of the check valve mechanism and holds the open state of the valve of the check valve mechanism when the gas is discharged from the tank. The check valve mechanism includes a valve seat, and the valve seat is disposed in the first flow path.

A pressure reducing valve includes a piston disposed in a cylinder chamber; a valve element that is coupled to the piston and opens and closes a valve seat; a valve spring that biases the valve element in a direction in which the valve element is moved away from the valve seat; and a biasing member that biases the valve seat toward a side opposite to the piston. The pressure reducing valve is configured to reduce a primary pressure of a fluid to a secondary pressure. The valve seat is disposed such that the valve seat reciprocates in the same direction as a direction in which the valve element reciprocates in the primary pressure chamber. As a difference between the primary pressure and the secondary pressure increases, the valve seat moves toward the secondary pressure chamber.

A solenoid valve device includes a body including a gas passage and an accommodation portion communicating with the gas passage, a solenoid valve that is accommodated in the accommodation portion and that controls flow of gas by opening and closing the gas passage, a sealing member disposed between the accommodation portion and the solenoid valve to maintain airtightness of the gas passage, and a solenoid that generates power for the solenoid valve to open and close the gas passage, wherein the body is provided with a communication hole that allows communication between inside and outside of the accommodation portion; the solenoid includes a connection terminal portion extending toward the communication hole; and a connector is accommodated in the communication hole in a manner such that rotation of the connector in a circumferential direction about an axis of the communication hole is suppressed.

A steering system is provided which more appropriately alleviates driver's discomfort in the wrists. A steering ECU has an estimated grip angle calculating circuit, a deviation calculating circuit, an automatic steering torque command value calculating circuit, and a grip angle command value calculating circuit. The estimated grip angle calculating circuit calculates an estimated grip angle based on a steering angle. The deviation calculating circuit calculates a deviation based on the steering angle, a steering angle deviation, and the estimated grip angle. The grip angle command value calculating circuit calculates a grip angle command value that is a sum of a grip angle and the deviation.

The control portion opens the pilot valve and closes the main valve when the detected temperature is equal to or lower than a first reference temperature.

Fuel supply system

A safety valve includes a cylinder having an open end and a plug for closing the open end with a hermetic seal. The interior of the cylinder communicates with a high-pressure gas passage. The cylinder is deformed as a function of gas pressure in the high-pressure gas passage to widen the open end. This allows gas in the high-pressure gas passage to escape and thus prevents the gas pressure from increasing beyond an acceptable level.

Safety valve and electromagnetic valve

A valve system includes a fusible plug valve that functions as a fusible plug valve and as a manual valve. When functioning as a fusible plug valve, the fusible plug valve opens at a high temperature to release gas from a high pressure tank to outside. When functioning as a manual valve, the fusible plug valve is opened manually to release the gas from the high pressure tank to the outside.
