Excess fuel is returned to the first one of the two fuel tanks. When the level in the first fuel tank is less than the level in the second fuel tank by a predetermined amount, the transfer pump transfers an amount of fuel from the second fuel tank to the first fuel tank. Fuel level sensors are utilized to monitor the level of fuel in the two fuel tanks and report to a microprocessor which controls the transfer pump. The microprocessor utilized to control the transfer pump may be incorporated into the transfer pump, may be a stand alone microprocessor, or may comprise an existing vehicle circuit board such as, e.g., the electronic control module (ECM). A fuel transfer line interconnects the two tanks and is located above the two tanks.

  • Patent number: 6668859
    Abstract: A collet assembly includes a collet and a tubular valve sleeve sleeved on a rotary shaft that is disposed within a stationary wall body and which defines a piston-receiving chamber. A piston is disposed movably in the piston-receiving chamber. The valve sleeve is formed with a valve opening therein, a valve chamber extending from the valve opening, a valve inlet in fluid communication with the valve chamber and a fluid injection passage in the stationary wall body, and a valve outlet in fluid communication with the valve chamber and a fluid channel in the shaft. A check valve is mounted in the valve chamber, and is moved to an open position, in which, the valve opening is opened due to injection of a high-pressure hydraulic oil into a clearance through the fluid injection passage, thereby permitting movement of the piston, which, in turn, results in clamping of the collet.

  • Patent number: 6648000
    Abstract: A spool for carrying continuous pipe or coiled tubing for a coiled tubing injector is dropped into a stand at a site and coupled to a rotary power source. The stand includes two axles, on either side of the spool, and a drive coupling. A pipe slideably extends through one of the axles. It is retracted when the spool is lowered onto the stand and then extended for communicating fluid between the coiled tubing and a fluid source. A swivel joint is connected to one end of the pipe. The pipe is permitted to turn with the spool or is held stationary with respect to the stand depending on whether the swivel joint is mounted outside the stand or inside the spool.

  • Patent number: 6637454
    Abstract: A fluid handling system is disclosed having a swivel for connecting a stationary fluid source line to a fluid service line that is wound upon a reel. A rotor cap secures the fluid source line and a rotor within the swivel in position, allowing a housing within the swivel to freely rotate with the fluid service line and reel. The swivel is coupled to the fluid source line using a crimping ferrule to eliminate the necessity of predisposing mating components on the fluid source line. The swivel is further provided with seals that reduce the incidence of bunching and tear due to the reduction in drag imposed on the seals.

  • Patent number: 6622676
    Abstract: A cylindrical element having a first axis and at least one internal longitudinal passage, and a circular circumferential groove formed in an outer surface of the element and having a second axis. The groove eccentric of the element such that the groove intersects the wall of the longitudinal passage, forming thereby a rectangular opening therebetween. When a second longitudinal passage is present, it is similarly intersected by a second eccentric groove spaced apart axially from the first groove. The axis of the second groove is rotationally displaced about the element axis from the first groove, preferably by a large angle, for example 180°, such that the first eccentric groove does not intersect the second passage, nor does the second eccentric groove intersect the first passage.
