  • Patent number: 9671008
    Abstract: An oil suction device including a primary suction port installed at an inflow end of a thin pipe for sucking oil in an oil storing section, and a third suction port formed in a gap between a first tapered surface and a second papered surface due to a relative movement of the thin pipe to the thick pipe. At a suction pressure of the oil pump less than a predetermined pressure, the oil suction device sucks only oil from the primary suction port, and at a suction pressure of the oil pump equal to or more than the predetermined pressure, air is sucked from the third suction port formed in a gap between the first tapered surface and a second tapered surface due to the relative movement of the thin pipe to the thick pipe.

  • Patent number: 7159575
    Abstract: Surplus fuel returns from an engine into the sub-tank through a bellows pipe. A downstream end of the bellows pipe is supported by a sub-tank lid that closes an opening of a sub-tank. One ends of arms engage with the top of a pump module, which includes a fuel pump. The other ends of arms engage with the outer peripheral wall of the sub-tank. Thereby, the arms connect between the pump module and the sub-tank. Surplus fuel flows into the sub-tank through the bellows pipe, and strikes against the arm. Thereby, return fuel, which comes back into the sub-tank, decreases in kinetic energy. Thus, sound and vapor generated from fuel in the sub-tank can be reduced when return fuel comes back into the sub-tank.

  • Patent number: 5779092
    Abstract: The tank and baffle system comprises a tank for transporting liquids, having a plurality of baffles for controlling surges and excess liquid movement produced by movement of the tank. The present invention is particularly useful where there is a large ratio of tank width to tank support and lateral bending loads may be in excess of longitudinal bending. The baffles are rigidly secured to a tunnel structure that spans longitudinally from the front to the rear of the tank, and forms a continuous structure in both longitudinal and transverse directions. A further aspect of the invention is the use of chamfered corners on the baffle plates to provide fluid communication between chambers of the tank, as well as to reduce surging of the liquid contents and reduce or eliminate joint fatigue. Access ports in the baffles that are covered by access covers during use are another aspect of the invention.

  • Patent number: 5575307
    Abstract: In a device for the disposal of liquid media, such as cooling-lubricating liquids containing production residue, such as chips from industrial processes, wherein these media can be returned via at least one pipe line to a return reservoir and from there through a pipe line connected near the bottom to at least one collecting tank by means of at least one return pump, it is intended to prevent deposits of production residue in the return reservoir and to clean it. This is accomplished in that the return reservoir has the approximate shape of a standing circular cylinder, in which at least one pipe line supplying liquid media terminates approximately tangentially. Because of this a circulating flow of the liquid media is generated in the return reservoir, which cleans the interior wall of the return reservoir and prevents the deposit of production residues.

    Abstract: A method and apparatus for measuring low fuel level in a fuel tank having a fuel pump with an anti-slosh pot supplied with fuel from a predelivery pump in the fuel pump. Fuel measurement is effected by sensing delivery of air to the anti-slosh put by the predelivery pump when the fuel level in the tank is low, and measuring the amount of fuel in the anti-slosh pot when delivery of air is sensed. The amount of fuel measured in the anti-slosh pot accurately represents the amount of fuel remaining in the fuel tank.

  • Patent number: 5000217
    Abstract: The invention relates to an apparatus for keeping a rain water well unfrozen. The apparatus comprises a cover (12), walls (13) and an outlet (15), which defines an air space (16) of the well above the outlet and a water space (17) of the well below the outlet. According to the present practice, the whole surface area of the water in a rain water well is in contact with open air, which results in that the well freezes relatively easily under the joint influence of wind and frost. This problem is solved according to the invention in such a way that the apparatus comprises a funnel (1) positioned under the cover (12) of the well and a flow tube (5), the cross section of which is substantially smaller than the diameter of the well and which tube extends from the lower part of the funnel (1) under the water surface of the well.

  • Patent number: 4792113
    Abstract: A flow limit valve for limiting the flow rate of a pressurized fluid includes a valve body with an interconnecting cavity of circular cross section. Within the cavity is a piston that slides within the cavity under force generated by a pressure differential across the piston to a closed position in engagement with a seat at the end of the cavity. A first encapsulated magnet is carried within the valve body in a chamber located on the side of the seat opposite the cavity. The first encapsulated magnet can be moved in response to another magnet outside the valve body to move a pin which can extend through the seat when the piston is in a closed position to thereby move the piston to an open position. The magnetic forces applied through the valve body affect internal valve operation via the pin and thus avoids the dange of noxious fluids escaping through sliding seals or flexible membranes.
