Abstract: Suction jet pumps include a driving line which leads via a jet outlet into a suction chamber, where the suction chamber has a suction opening which interacts with a valve element and through which fluid is sucked into the suction chamber. The valve element together with the suction opening forms a suction valve. The suction jet pump is driven by a driving stream flowing via the driving line. The suction jet pump is arranged in a storage tank and sucks fuel out of a fuel tank into the storage tank. The driving line has a bypass opening which leads into the suction chamber and is arranged in such a manner that the bypass stream thereof acts on the valve element.

Abstract: Suction jet pumps are already known with a driving line which leads via a jet outlet into a suction chamber, where the suction chamber has a suction opening which interacts with a valve element and through which fluid can be sucked into the suction chamber. The valve element together with the suction opening forms a suction valve. The suction jet pump is driven by a driving stream flowing via the driving line. The suction jet pump is arranged in a storage tank and sucks fuel out of a fuel tank into the storage tank. At low levels in the fuel tank, air may sometimes be sucked up and conducted into the storage tank, as a result of which foaming occurs in the storage tank. However, the large volume of the foam causes fuel to be displaced, which may result in partial emptying of the storage tank. This effect is also referred to as dynamic leakage. A characteristic curve of the suction jet pump that represents the suction power as a function of the driving stream has a comparatively steep gradient.

Abstract: A field programmable gate array (FPGA) and methods for executing operations using an FPGA are provided. The method includes providing a first dynamic macro and a second dynamic macro in the FPGA. The first dynamic macro and the second dynamic macro each represent logic within the FPGA that can be reconfigured. The method further includes executing a first operation associated with the user application using the first dynamic macro; reconfiguring the second macro to execute a second operation associated with the user application prior to completion of the first operation; and upon completion of the first operation, executing the second operation using the second dynamic macro.
