Abstract: A recording apparatus includes a conveyance unit that conveys a recording medium in a first direction toward a recording head for ejecting a liquid, a tank including a containing chamber containing the liquid to be supplied to the recording head, and an injection port through which the liquid is injected into the containing chamber, the tank being disposed downstream of the conveyance unit in the first direction, a rotatable lever that holds a tank cap for closing the injection port, and a cover that rotates about a rotation shaft between an open position for exposing the lever and a closed position for covering the lever, the rotation shaft being disposed upstream of the conveyance unit in the first direction. The cover includes a sliding portion that is provided on a surface facing the lever and comes into contact with the lever while the cover is rotating toward the closed position.

Abstract: A technique capable of certainly suppressing adhesion of waste ink to hands, clothes, and the like during replacement of a waste ink tank is provided. There are included a container portion provided with an insertion port which a discharge member discharging waste ink can be inserted into and pulled out from and a shielding portion movable between a shielding position where the insertion port is shielded and an open position where the insertion port is opened.

Abstract: A recording apparatus includes a tank including a chamber configured to store liquid to be supplied to a recording head that ejects the liquid and a filling port from which the liquid is injected into the chamber, and an injection auxiliary member configured to assist injecting of the liquid into the chamber from the filling port, the injection auxiliary member including a first and a second flow channels each defined by a first or a second upper end portion that opens toward outside of the tank and a first or a second lower end portion that opens toward inside of the tank, wherein the second flow channel has an expansion portion arranged in a middle portion between the second upper end portion and the second lower end portion and configured to form a step to expand a cross-sectional area.

Abstract: In an internal combustion engine for a vehicle having a drive clutch, a blowby control system includes a fresh air introducing channel, for introducing fresh air into a crankcase, and a blowby gas return channel for returning blowby gas from the crankcase to an air-intake system. A blowby control valve is provided in the fresh air introducing channel or the blowby gas return channel, for selectively restricting gas flow through the blowby system. A controller is also provided on the vehicle for controlling operation of the blowby control valve. The controller is programmed to switch the blowby control valve from the closed state to the open state, with the drive clutch connected, when the vehicle starts traveling. The blowby control system and method hereof can reduce variations in the engine speed occurring during engine idling and before clutch engagement, to improve ride quality of the vehicle.

Abstract: A blowby gas ventilation system for an internal combustion engine capable of preventing oil from being diluted by efficiently and quickly exhausting a blowby gas together with a water content and the like from a crank chamber through forced ventilation of the crank chamber. The blowby gas ventilation system is intended for a four-stroke-cycle internal combustion engine. The system includes a fresh air introduction pipe, through which fresh air is sent from an outside of the internal combustion engine through a throttle portion to a crank chamber. The system also includes a blowby gas return passageway, through which the blowby gas is returned back to a downstream side of an air cleaner.

Abstract: A fuel injection device is installed in a cylinder head of an internal combustion engine in such a manner that a fuel injection port thereof faces a curved intake passage formed in the cylinder head. Fuel is injected from the fuel injection device directly toward a wall surface of the intake passage without aiming at an intake port.
