A sump tank for use with a gas turbine engine in offshore conditions is disclosed. In embodiments, the sump tank includes two circuitous lubricant flow paths. Each flow path includes an end compartment, a side compartment, and a tube that feed to a central compartment. The baffles used to form the central compartment are angled so as to cause the lubricant entering from the tubes to swirl, which may increase the residence time of the lubricant and may help ensure that any entrained air is released from the lubricant prior to entering the suction line.

An apparatus and method of transporting a turbine engine with a transportation fixture including a turbine engine jig having mounts for securing the turbine engine, a rotor with a drive shaft rotationally supported by a bearing, the method includes supplying a lubricant to the bearing and rotating the drive shaft while the turbine engine is in transport.

A suction device may include a suction channel, a first valve, and a second valve. The suction channel may include a first suction portion and a second suction portion disposed opposite one another in a transverse direction. The first valve may be arranged in the first suction portion. The first valve may include a first valve seat and a moveable first valve body. The second valve may be arranged in the second suction portion. The second valve may include a second valve seat and a moveable second valve body. When a transverse acceleration is equal to or greater than a predefined transverse acceleration, one of the first valve and the second valve may close while the other one of the first valve and the second valve remains open. When the transverse acceleration is less than the predefined transverse acceleration, the first valve and the second valve may both be open.

A personal watercraft comprises a body; a driving power source mounted in the body; a water jet pump driven by the driving power source to eject a water jet in a rearward direction; a handle bar gripped by a rider; a rider operation member provided on the handle bar, the rider operation member being operated by the rider to be movable to an acceleration position for providing a forward movement command, a deceleration position for providing a rearward movement command, and a neutral position for providing an idling command, the neutral position being set to a position between the acceleration position and the deceleration position in a movement path of the rider operation member; and a control unit which controls the driving power source in response to the rider's operation for moving the rider operation member.

A preventing apparatus for concentrating oil of a vehicle includes: a chamber disposed in an oil pan to enclose the surrounding of an oil strainer and having both sides provided with through holes through which oil inflows and outflows; and an oil blocking module disposed to be spaced apart from the through holes in the chamber and operated in an opposite direction to a turning direction of the vehicle when the vehicle turns in order to block one of the through holes of the chamber.

An oil pan in an engine assembly comprises a housing including a bottom wall and a sidewall and an oil drain tube. The oil drain tube includes a tubing wall and a portion of the sidewall and is integrally formed with the housing.

A fluid delivery system includes a reservoir for storing fluid, a rotary pump having a first pump port and a second pump port, a first fluid conduit connecting the first pump port to the reservoir, and a second fluid conduit connecting the second pump port to the reservoir. The rotary pump rotates in a first delivery direction in a normal mode and in a second delivery direction in an alternative mode. A first valve separates the first pump port from the reservoir when the rotary pump is in its alternative mode, and a second valve separates the second pump port from the reservoir when the rotary pump is in its normal mode.

A handheld four-stroke engine lubricating system comprises: an oil storage chamber formed by a bottom casing and a lower tank body, a crankshaft chamber formed by the lower tank body and an upper tank body, an air valve chamber formed by the upper tank body and a cylinder head cover, a cam chamber formed by the upper tank body and a cam chamber cover, and a tappet chamber connected between the air valve chamber and the cam chamber. The two sides of the upper and lower tank bodies are correspondingly provided with a first and a second oil inlet passages communicated with the oil storage chamber and the crankshaft chamber. The first and the second oil inlet passages are correspondingly provided with first and second check valves thereon. The first oil inlet passage is connected to a hose pressed against the bottom casing.

A variable compression ratio internal combustion engine is equipped with a variable compression ratio mechanism that changes an engine compression ratio depending on the rotational position of a first control shaft arranged in an oil pan, and an actuator that changes and holds the rotational position of the first control shaft, and a linking mechanism configured to link the actuator and the first control shaft. The linking mechanism has a lever linked to the first control shaft, and a connecting pin configured to rotatably link the tip of an arm part extending radially outward from the center of the first control shaft and one end of the lever. At least when having been set to the highest compression ratio, the first connecting pin is configured to be submerged below an oil level of the oil pan.
