摘要： A piston pump for pumping fuel in which a risk of fuel getting into the area of a shaft seal is limited. The fuel pump includes a separation chamber which is provided between a shaft seal and a fuel chamber that contains fuel. Located in the separation chamber is for instance air as a separator means, and the separation chamber communicates with an air inlet of the engine. This assures that fuel cannot get into the area of the shaft seal or escape to the outside. The fuel pump is suitable in particular for internal combustion engines in which the fuel must be delivered at high pressure.

摘要： The device relates to a piston pump, in particular a high pressure pump for a fuel injection device of an internal combustion engine, with at least one piston that is supported so that the piston can slide in a piston guide provided in a housing. A drive shaft is supported in the housing (10) on which drive shaft a crank element is provided. A stroke ring is supported in rotary fashion on the crank element and the piston can be acted upon by the drive shaft by way of this stroke ring. In order to prevent high lateral forces on the piston, the piston is supported on the non-rotating stroke ring with a sliding surface disposed on it against an associated slide bearing surface, wherein lubrication grooves are let into the slide bearing surface, crosswise to the relative motion between the piston and the stroke ring.

摘要： The temperature of a measuring resistor is controlled for measuring the mass flow rate of intake air entering an internal combustion engine. The operating temperature of the measuring resistor is regulated by controlling the level of electric current flowing therethrough. A voltage signal based on the level of electric current flowing through the measuring resistor is generated which is indicative of the mass flow rate of air entering the engine. The operating temperature of the measuring resistor is adjusted based on the value of the voltage signal, to optimize the measurement sensitivity thereof based on the level of the intake air mass flow rate.

摘要： A flow rate meter for determining the mass or flow rate of flowing air, having a temperature-dependent measuring resistor disposed in an air bypass conduit. The air bypass conduit has a convergent portion in the region of the measuring resistor in which the air flow is accelerated. As a result of the air flow the effects of any air disturbances upon the measuring element are reduced. The following geometric relationships are advantageous: l.sub.1 /l.sub.s >3.8, l.sub.1/2 >1.5, l.sub.1 /1.sub.3 >2.0, l.sub.1/4 >9.0, l.sub.5 /l.sub.s >1.5, l.sub.5 /l.sub.6 =1.7 to 1.9, b.sub.1 /b.sub.s >40.0, b.sub.1 /b.sub.2 >2.0, l.sub.1 /b.sub.1 >3.5, and l.sub.5 /b.sub.3 =5.5 to 6. The air flow rate meter is especially suitable for determining the mass or flow rate of aspirated air in mixture-compressing engines with externally supplied ignition as well as air-compressing, self-igniting engines.

摘要： The invention relates to an axial piston pump with at least one pump element, which includes a piston disposed in a housing, with a drive shaft upon which a swash plate for driving the piston is disposed. The swash plate is non-rotatably fixed, but can pivot around a swash plate pivot axis which extends perpendicular to the longitudinal drive shaft axis (A), and with a device for adjusting a pivot angle between the drive shaft and the swash plate. In order to be able to adjust the oblique position of the swash plate in a simple manner, even during pump operation, it is provided that the device for adjusting the pivot angle of the swash plate has a displacing device disposed in a stationary manner on the housing. The displacing device acts on the swash plate via an intermediate member, which rotates jointly with it, on one end of the swash plate pivot axis to adjust pivot angle of the swash plate in the axial direction of the drive shaft so that the swash plate is secured in the adjusted pivot position when the drive shaft rotates.
