摘要： A check valve that can prevent sticking of a valve body and reliably perform an opening and closing action in a check vale having a simple structure and that does not use biasing means on the valve body. A check valve has support pieces of a valve body protruding in the valve body direction on a circular base seat forming an outflow window in the center inserted in a circular groove where a support member (retainer) is formed between an outflow opening and a valve seat and on an open edge of the outflow window formed in the center of the base seat, and the support pieces of the support member (retainer) that support the valve body have linear or planar support parts on the top portion for leveling at least in a radial direction of the base seat.

摘要： A fuel system that in at least some implementations includes a carburetor having a fluid passage, a solenoid, a valve, a driver circuit and a control circuit. The valve may be moved by the solenoid between an open position permitting fluid flow through the fluid passage and a closed position at least partially inhibiting fluid flow through the fluid passage. The driver circuit and control circuit are communicated with the solenoid to contribute to providing power to the solenoid and controlling actuation of the solenoid. The driver circuit and control circuit provide a first magnitude of power to the solenoid to initially change the solenoid from its closed position to its open position and a second magnitude of power to maintain the solenoid in its open position wherein the second magnitude of power is less than the first magnitude.

摘要： A composite control valve is constructed by a valve housing, a negative pressure working chamber defined in the valve housing to communicate with a negative pressure generating section in the engine, a first control valve operable to be opened and closed with generation and extinction of a negative pressure in the negative pressure working chamber, and a second control valve operable to be opened and closed with the generation and losing of the negative pressure in the negative pressure working chamber. The first control valve is incorporated into an air vent system which provides communication between an upper space in a fuel tank and the atmosphere, and the second control valve is incorporated into a fuel passage system which provides communication between a portion of the fuel tank below a fuel oil surface and a fuel supply section in the engine. At least a portion of the air vent system is constituted by an inner air vent pipe disposed within the fuel tank, and a gas-liquid separating device is provided in an opening of the inner air vent pipe into the upper space. Thus, upon stoppage of the operation of the engine, not only the fuel passage system but also the air vent system leading to the upper space in the fuel tank can be blocked simultaneously, to prevent release of evaporated fuel generated in the fuel tank to the atmosphere.
