摘要： The present invention teaches methods of operating a pressurized cryogenic liquid gas storage tank that has a vent cooling shield around which fuel vented from a storage tank flows to cool the storage tank by reducing the influence of heat influx into the storage tank. The method of the present invention provides for reduction in the quantity of fuel loss during the venting operation and allows a greater volume of liquid fuel to be stored in the storage tank. The method includes allowing fuel in a storage tank to transition between a two-phase state of liquid and gas into a single-phase state of liquid and back into a two-phase state of liquid and gas. Additionally, the present invention allows filling a storage tank to a liquid level greater than about 95% of the capacity of the storage tank.

摘要： An axial piston machine includes a housing and a rotary shaft is mounted in the housing. A plurality of radially spaced cylindrical bores are arranged concentrically around the shaft and a reciprocal piston is located in each bore. A plate is located at an angle of inclination with respect to the rotary shaft. Each piston is connected to the plate by a support body locator and first and second support bodies are located in the support body locator and are in contact with the opposed surfaces of the plate.

摘要： In axial plunger pump of the type wherein a swash plate is rotated while a cylinder body is kept stationary, plungers are axially slidably inserted into respective cylinder bores in the cylinder body, and the rotating swash plate cooperates with the plungers to obtain an axial stroke movement thereof for a pump operation. A stopper member is provided for cooperation with the plungers so that the stroke movement of the plunger in a direction toward the swash plate is limited. An actuator is provided for controlling an axial position of the stopper plate for obtaining desired variations of the effective stroke of the plungers.

摘要： An axial piston pump for pumping a medium such as a viscous liquid in which a wobble element is set into rotating movement via a piston, the wobble element moving at least one feed piston in a piston bore. The piston bore is intended to communicate, via a transverse line and a further piston bore which is occupied by a control piston, with an intake line for the medium to be pumped. By means of this axial piston pump, which is valve-controlled on the compression side and slide-controlled on the intake side, liquid having a high viscosity can be pumped without a loss of efficiency, and any noise produced by the pump can be reduced. These latter advantages are reinforced still further provided the feed system is received in a pump insert that is supported with respect to a pump housing by means of elastic bearing elements.
