摘要: In an apparatus for supplying a fuel to a vehicular combustion heater which supplies the fuel from a fuel tank via a fuel pump to the heater which is mounted on an electric vehicle, discharging into atmosphere of fuel vapor from the fuel tank is restricted to the best extent possible. For that purpose, prevention is made of that discharging from the combustion heater of the fuel vapor which is likely to occur when the set pressure for opening a positive pressure valve in a two-way valve for the fuel tank is set high. Interposed in series between the fuel pump and the combustion heater is a one-way valve which opens when the internal pressure in the fuel supply passage has risen to a predetermined set pressure which is higher than the set pressure for opening the positive pressure valve, and a solenoid valve which is opened when the combustion heater is in operation. The solenoid valve is arranged such that the leak pressure to cause the fuel to leak through the solenoid valve at the time when the solenoid valve is kept closed is higher than the set pressure for opening the one-way valve.

摘要: The following technical means is provided to achieve a chain shift operation with a minimum of the guide pulley travel distance, to improve speed change efficiency and operatability, and to prevent the speed change assembly from protruding sideward:At a forward location of a sprocket cluster (2), a link base (8) of a pantograph link mechanism (12) is supported by a chain stay (7), and from this, an inner link (9) and an outer link (10) are extended. To respective free end portions of these links, there is connected a movable member (11), which pivotally supports a chain guide (15) which is elastically urged. The guide pulley travel control means (18) functions in such a way that when the pantograph link mechanism (12) is deformed, it would cause a guide pulley (13) of the chain guide (15) to move inward axially of the hub shaft and at the same time forwardly downward substantially along a radial path of the sprocket cluster (2).
