Title: Fuel feed system for fuel-injected IC engine with fuel pressure control
Inventor: YONEKAWA MASAO
IPC: F02M69/46
Filed: 1996-01-10
Abstract: The fuel feed system has a fuel pump (22) with a variable speed drive (26) in the fuel tank (21) to feed fuel to the injectors (20) via a filter (25). A pressure sensor (28) behind the fuel filter provides actual pressure values for the fuel feed. A feedback control system regulates the fuel pump speed to ensure a steady fuel pressure at the injectors. This fuel pressure is computed from the engine loading. The control system monitors the fuel injection pulse length and varies same to match the required engine torque. Monitoring the pressure variations during fuel feed enables the control circuit to determine if air or vapour bubbles are in the system. In this case the overall pressure of the feed system is enhanced.

Patent DE-19629947-A1 (DE)
Inventor: FEHLMANN WOLFGANG
IPC: F02M41/14
Filed: 1996-07-25
Abstract: A fuel injection pump has an injection adjusting piston (10) which adjusts the injection beginning. The injection adjusting piston (10) is exposed during its operation to tilting moments because of its eccentric articulation to a part (3) of the cam drive of a fuel injection pump designed as a distributor injection pump. In addition, the injection adjusting piston (10) is exposed to further forces which derive from a radial hydraulic medium supply (55) at the side of the injection adjusting piston (10) opposite to its articulated joint. Together with the tilting moment forces, these further forces exercise high unilateral pressing forces in the radial direction on the injection adjusting piston. By providing a second pressure field (57), said forces which act on the injection adjusting piston (10) are compensated for and the injection adjusting piston (10) is subjected to a substantially reduced radial stress.

Patent DE-19635719-A1 (DE)
Inventor: MAIER JAKOB
IPC: A01J5/08
Filed: 1996-09-03
Abstract: The invention concerns a rubber teat element with a head part which is substantially rotationally symmetrical to a longitudinal axis and has a teat-introduction opening, a retaining edge for engaging over a milking cup sleeve, and a suction connection piece connected to the head part, the latter merging at its end opposite the teat-introduction opening into the retaining edge. The side of the head part (3) is formed such that it is reinforced in a region (18) between the teat-introduction opening (49) and the transition area where it merges into the retaining edge (8), the upper end of the suction connection piece opening into this reinforced part of the head part. The part of the rubber teat element head lying between the reinforced part and the retaining edge is formed so as to be at least partially resilient. During the suction phase, a pressure force acts on the head part region between the reinforced part (18) of the head part (3) and the retaining edge, which pressure force attempts to move this part towards the outer side of the suction connection piece. This generates an upward movement of the milking cup sleeve whilst, in the pressure relief phase, it produces a slight downward movement of the milking cup sleeve with respect to the teat.

Patent DE-19652595-A1 (DE)
Inventor: WIESBECK WERNER PROF DR ING
IPC: H01Q13/04
Filed: 1996-12-18
Abstract: The invention relates to a high-mode operating resonator, e.g. a coaxial waveguide, wherein various oscillation modes of an electromagnetic field are coupled in and superimposed on each other. The mixed mode thus arising from the excitation field is used to excite an antenna, preferably a biconical antenna. The azimuthal emission characteristic of the electromagnetic wave emitted by the antenna has the same dependency as the azimuthal field distribution in the resonator. The emission characteristic has in particular, in the case of an azimuthal and anisotropic excitation field, privileged directions in the azimuthal emission. A change of direction of the maximum emission of the electromagnetic wave occurs through an additional change of the phase or amplitude relationships between the coupled electromagnetic field modes.
