Dual fuel tank system with internally mounted fuel tanks in line with actuators
A machine includes an engine compartment, an engine located within the engine compartment, a first compartment located on a first side of the machine, external to the engine compartment, and accessible via the engine compartment, as well as a second compartment located on a second side of the machine, external to the engine compartment, and accessible via the engine compartment. A first actuator is disposed on the first side of the machine and couples to a first linkage member that supports a work implement. A second actuator is disposed on the second side of the machine and couples to a second linkage member that supports the work implement. A first fuel tank is located in the first compartment, coplanar with the first actuator. A second fuel tank is located in the second compartment, coplanar with the second actuator.
Fuel pump module
The present disclosure relates to a fuel pump module, and more particularly, to a fuel pump module including a flange module and a reservoir module, in which when a fuel delivery pipe for supplying filtered fuel from the reservoir module to the flange module is coupled to the reservoir module, since the fuel deliver pipe may be coupled to the reservoir module to a desired position in an axial direction and to be prevented from rotating in an axial direction, the fuel delivery pipe may be prevented from interfering with a guide rod connecting the flange module and the reservoir module in a vertical direction, thereby not only preventing the occurrence of fire, but also increasing a common use rate of the reservoir module.
Fuel tank and pump system
An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.
Fuel supply device
A fuel supply device includes a fuel supply passage, a fuel pump, a pressure-regulating valve, and a housing. The fuel supply passage is in communication with the fuel injector. The fuel pump pumps the fuel to the fuel supply passage. The pressure-regulating valve regulates the pressure of the fuel in the fuel supply passage. The housing is disposed in the fuel tank. The housing accommodates the fuel pump and the pressure-regulating valve. The fuel supply passage is formed within the housing. The pressure-regulating valve is connected to an end portion of the fuel supply passage formed in the housing. The volume of the end portion of the fuel supply passage in the housing is configured to increase with increasing pressure of the fuel.
PROTECTION STRUCTURE FOR FUEL PUMP CONNECTION PART
A protection structure for the fuel pump connection part includes a top plate 20 that has fuel pump connection parts 23, 25, and a cover member 30 that covers the top plate 20 and the fuel pump connection parts 23, 25. The cover member 30 includes a top plate cover part 31, hole parts 39, 41, and connection-part cover parts 45, 55. The top plate cover part 31 and the connection-part cover parts 45, 55 are integrally formed. The connection-part cover parts 45, 55 includes movable parts 47, 57 that move with respect to the top plate cover part 31, and the fuel pump connection parts 23, 25 are exposed in a state where the movable parts 47, 57 have moved in a separating direction from a front surface side of the top plate cover part 31.
Fuel supply device
A fuel supply device is insertable into a fuel tank through an opening formed in an upper wall of the fuel tank in an insertion direction. The fuel supply device includes a flange unit and a pump unit coupled to the flange unit. The pump unit includes a guide member extending in the insertion direction. The guide member is configured to abut on an opening periphery so as to guide the pump unit when the pump unit is inserted into the fuel tank. A guide surface of the guide member includes a concave surface.
Cover for fuel tank
A cover for a fuel tank includes a flange unit configured to close an opening of the fuel tank and a joint member movably coupled to the flange unit. The joint member is configured to move in an upward/downward direction relative to the flange unit. Two side tubular portions extend from the flange unit in the upward/downward direction and are positioned side-by-side. Column portions extend in the upward/downward direction from the joint member. The column portions are moveably disposed in the side tubular portions. The column portions are configured to move in the upward/downward direction relative to the side tubular portions. The side tubular portions are connected to each other via a rear side wall and a front side wall of a center tubular portion disposed between the side tubular portions.
Intake Arrangement
Intake arrangement for an internal combustion engine for the intake of a liquid medium from a container, having a strainer, via which liquid medium can be taken in from the container, and having at least one suction pipe which opens with a first end into the strainer and via which the liquid medium can be delivered towards a suction pump, which interacts with the respective suction pipe. The suction pipe is mounted at a second end that faces away from the strainer such that it can be pivoted about an axis such that the suction pipe follows a movement of the liquid within the container.
TANK LID UNIT AND FUEL SUPPLY DEVICE
A total dimension of spacing dimensions of a gap provided by a metal rod on a side opposite to a metal housing in a first assembling structure and a second assembling structure is set to be larger than a difference in a thermal expansion amount between a resin lid main body and the metal housing in a reference radial direction when a temperature exceeds a reference temperature. A total dimension of each of a spacing dimension of a gap provided by the metal rod on a side toward the metal housing and a spacing dimension between a resin protrusion and the metal housing in the first assembling structure and the second assembling structure is set to be larger than a difference in a thermal shrinkage amount between the resin lid main body and the metal housing in the reference radial direction when a temperature falls below the reference temperature.
FUEL TANK AND PUMP SYSTEM
An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.
