摘要： A valve body has an inflow passage for a working fluid, an outflow passage for the working fluid, and a pressure relief passage, which connects the inflow passage and the outflow passage by bypassing a normally close valve seat. A pressure relief valve is located in the pressure relief passage. The pressure relief valve closes the pressure relief passage, if a pressure of the working fluid in the outflow passage is lower than, is equal to, and is higher by a pressure difference less than a predetermined relief pressure than a pressure of the working fluid in the inflow passage. The pressure relief valve opens the pressure relief passage, if the pressure of the working fluid in the outflow passage is higher by a pressure difference equal to or higher than the relief pressure than a pressure of the working fluid in the inflow passage.

摘要： An electromagnetic valve is configured with an electromagnetic section, a flow path section, and a sealing member between them. This separate arrangement improves a degree of freedom for arranging inflow and/or outflow passage. This separate arrangement also enables to reduce a size of the electromagnetic section. A plunger comes in contact with a central portion of a spherical portion of a valve member. A normally open compression spring comes in contact with a peripheral portion of the valve member. The valve member can be reliably seated on the normally close valve seat even if the plunger is slightly tilted.

摘要： A solenoid valve includes a housing, a valve element provided in the housing to open and close a valve port, and a resin-molded guide member that includes a support portion supporting the valve element to be slidable in an axial direction, and an attachment portion attached to and in contact with an inner side of the housing. The guide member further includes an intermediate joint portion connecting the attachment portion and the support portion. The attachment portion is larger in shape in an orthogonal direction orthogonal to the axial direction than the intermediate joint portion. The support portion extends in the axial direction from the intermediate joint portion. The guide member has an injection-molding gate mark on an outer face of the attachment portion.

摘要： A control device transmits an opening degree command amount to an actuator to command an opening degree of a sealing valve. The control device sets a pressure difference between a tank-side pressure and a canister-side pressure to a specified value or more. The control device causes a pressure variable device to change the canister-side pressure to form a state in which the pressure difference becomes equal to or higher than a specified value while the sealing valve is closed. The control device learns a valve opening start amount based on the opening degree command amount when the tank-side pressure changes in response to the opening degree command amount that gradually increases from zero. The control device determines the opening degree command amount based on the valve opening start amount, which has been learned.

摘要： A vehicle presence notification apparatus notifying a presence of a vehicle includes an alarm device and a dynamic speaker. The alarm device includes an alarm generator generating an alarm sound and an acoustic tube through which the alarm sound is emitted outside of the vehicle. The dynamic speaker generates a notification sound with audible frequency. The dynamic speaker is fixed to the acoustic tube and emits the notification sound inside of the acoustic tube, such that the notification sound is generated outside of the vehicle through the acoustic tube.

摘要： An electrical horn includes a horn housing, an oscillation member located at the horn housing to generate a sonic wave, and a resonance tube in which the sonic wave generated by the oscillation member flows. In the electrical horn, the resonance tube has a plurality of sonic outlet portions that are open in different directions. Accordingly, when the electrical horn is mounted to a vehicle, it is possible to reduce an amount of foreign material entering into the resonance tube while increasing a sonic pressure toward a vehicle front side.

摘要： An evaporated fuel processing device includes: a canister configured to adsorb fuel evaporated from a fuel tank; a vapor pipe connecting the fuel tank to the canister; a sealing valve provided in the vapor pipe to be driven by an actuator to quantitatively control an opening degree; and a controller. The controller includes: a restoration detector configured to detect that the supply of power from a battery to the controller is restored after the supply of power from the battery to the controller is cut off; and a restoration actuator configured to drive the actuator so that the sealing valve is fully closed or fully opened when the restoration detector detects that the supply of power is restored.

摘要： A check valve device includes a valve portion elastically deformable to prevent or allow a flow of a vapor fuel through a fluid passage in one direction by contacting with or separating from a valve seat. An upstream passage forming member has the valve seat and the fluid passage located upstream of the valve portion. A downstream passage forming member includes a terminal portion housed in the upstream passage forming member and having a downstream passage. A narrowed passage provided inside the terminal portion or between the upstream passage forming member and the terminal portion. A cross-sectional area of the narrowed passage is set to be smaller than any of the fluid passage and the downstream passage.

摘要： A fuel vapor purge system includes: a fuel tank; a canister; a passage component that defines an intake passage of an internal-combustion engine; a purge pump pumping vapor fuel; and a valve device having a valve object, a main part having an internal passage, an inflow port through which the vapor fuel pumped from the canister flows into the main part, an outflow port connected with the inflow port through the internal passage and being opened to the intake passage, and a leak port connected with the inflow port through the internal passage and being opened to outside of the main part. The leak port has a leak preventive structure which prevents the vapor fuel from leaking to outside when the valve device is attached to the passage component such that the vapor fuel is able to flow into the intake passage.
