A marine vessel includes at least one gas fuel consumer is arranged at a first horizontal level in the vessel, and at least one gas tank for the gas fuel consumer is arranged at a second horizontal level in the vessel, which second horizontal level is different from the first horizontal level. The vessel is provided with a fluid passing shaft for providing a confined vertically extending shaft between a gas consumer at a first horizontal level in the vessel and at least one gas fuel tank arranged at a second horizontal level in the vessel.

A damping assembly in a vehicle is provided. The damping assembly comprises a rod; a spring disposed along a lengthwise direction of the rod; and a buffer pad including a connection end coupled to the rod and an external end opposing the connection end and including a buffer surface. The spring is coupled with the rod and configured to be retracted and extended with the rod at the lengthwise direction.

A deformation inhibiting device for inhibiting deformation of a fuel tank includes a strut member. The strut member includes a bottom support portion and a top support portion configured to support a bottom wall portion and a top wall portion, respectively, of the fuel tank when the strut member is disposed within the fuel tank. The strut member is deformable or movable between an arrangement state for arrangement within the fuel tank and an insertion enabled state configured to be inserted into the fuel tank via the opening.

A method for manufacturing a strainer, such as a strainer of an ejector used to transfer fuel between two tanks of an aircraft or to supply fuel to an engine is provided. The strainer includes a conduit whereof a first end is intended to be connected to an inlet of the ejector, and whereof a second end is located within a housing including an open face for the passage of fuel, the open face being closed off by a grate acting as a filter. The method includes the step of manufacturing the conduit, the housing and the grate of the strainer as a single monobloc part.

A valve element includes: a loosely insertable wall portion that is loosely inserted in an inside of a connecting portion on a downstream side of a valve seat; a fittable tubular portion that is fitted to the inside of the connecting portion on a downstream side of the loosely insertable wall portion; and a projecting annular portion-that projects from the fittable tubular portion toward a radially inner side of the fittable tubular portion. An outlet portion projects into the fittable tubular portion. A valve spring is located on a radially outer side of the outlet portion and on the radially inner side of the fittable tubular portion to urge the valve element toward the valve seat.

An engine device having gas injectors attached to an intake manifold fixed to a side surface of a cylinder head. A fuel gas injected from the gas injectors is premixed in the intake manifold, and the resulting gas is supplied to a plurality of cylinders and ignited by ignition devices. The intake manifold has a configuration in which a plurality of intake branch pipes communicating with the cylinders are branched from an intake collecting pipe at an air supply side. The intake branch pipes include bent portions. In the bent portions of the intake branch pipes, inside inner walls near the cylinder head are bent at an acute angle.

Provided is power work equipment using a fuel container and/or a lubricating oil container that is/are easily replaced for the power work equipment, and supply(ies) liquid fuel and/or lubricating oil optimized for driving. A chainsaw (1A) (power work equipment) includes a main body (10) having an internal combustion engine (50), and a fuel container (90A) and/or a lubricating oil container (100A) detachably attached to the main body (10). A connection part (92) of the fuel container (90A) is connected with the fuel suction unit (60) in a liquid-tight manner, and the bag (91) is configured to collapse as liquid fuel (F) in the bag (91) decreases. A connection part (102) of the lubricating oil container (100A) is connected with a lubricating-oil suction unit (70) in a liquid-tight manner, and a bag (101) is configured to collapse as lubricating oil (L) in the bag (101) decreases.

A bracket includes: a fastener fixed to an engine by a fastening member; and a protector that is disposed between a high-pressure fuel pump (fuel system component) and a vehicle body frame (vehicle body component) opposed to the high-pressure fuel pump, and covers the high-pressure fuel pump continuously from the fastener. The protector includes: an inclined section that is located more upward at a position further in a direction away from the vehicle body frame; and a curved surface section that is curved between the fastener and the inclined section.

A controller of a fuel system for a vehicle is provided in which heat is dissipated outside from a printed circuit board to cool the controller. The dissipated heat is utilized to maximize the efficiency of the purge operation using a canister by waste heat. The controller is integrated with an air filter for removing foreign substances from air to be suctioned into a canister, and is configured to realize heat exchange between air passing through the air filter and a motor driver.

A fuel booster system having a fuel inlet port, a fuel outlet port, and a fuel accumulator fluidically coupled to both ports. The fuel inlet port allows fuel to be delivered to the fuel accumulator and the fuel outlet port is in fluid communication with a combustion engine to deliver fuel from the fuel booster system to the combustion engine. A source of pressurized gas is also fluidically coupled to the fuel accumulator to deliver pressurized gas through a gas port in one end of the fuel accumulator. A piston is located within the fuel accumulator and the source of pressurized gas can be discharged into the fuel accumulator to force accumulated fuel from the fuel accumulator and to the engine when the fuel booster system determines that the engine needs more fuel.
