Definitions
- the invention relates to a fuel injection pump for internal combustion engines, with a pump housing, in which a conveyor is housed, the operation of which is controlled with the aid of a control unit, which is housed in a control unit housing which is mounted on the pump housing.
- Such an injection pump is known from DE-OS 34 03 073 AI.
- the fuel to be delivered is passed through the control unit housing for cooling.
- Control unit housing proved problematic.
- the object of the invention is to ensure adequate cooling of the control unit housing without fuel being flushed around electronic components contained in the interior of the control unit housing.
- the object is in a fuel injection pump for internal combustion engines, with a pump housing in which a conveyor is housed, the operation of which is controlled with the aid of a control unit which is housed in a control unit housing which is connected to the Pump housing is mounted, solved in that a cavity is formed between the top of the pump housing and the underside of the control unit housing, into which a fuel inlet opens and from which a connecting line to the delivery device extends, and in that a filler with at least one in the cavity Deflection channel is arranged, via which the delivered fuel passes from the fuel inlet to the underside of the control unit housing.
- a special embodiment of the invention is characterized in that a mask is formed on the filler piece which, when the filler piece is installed, surrounds the fuel inlet in the pump housing.
- the mask ensures that the fuel from the fuel inlet reaches the deflection channel. 'Through the mask is prevented from' which the fuel in the form of a kind of short-circuit flow in a direct way from
- a further special embodiment of the invention is characterized in that the deflection channel starts from a tab which is formed on the filler piece and, in the installed state of the filler piece, is accommodated in a pocket which is excluded in the area of the fuel inlet in the pump housing. The effect of the mask is improved on the one hand. On the other hand, the tabs held in the pockets serve to hold the filler in position when installed.
- a further special embodiment of the invention is characterized in that an inlet tulip is formed in the surface of the filler piece facing the control unit housing, which is in connection with the connecting line in the pump housing when the filler piece is installed. The inlet tulip acts as a funnel and ensures that the fuel is sucked in at the top and air bubbles are prevented. Nevertheless, air present in the cavity is distributed in the sucked fuel in the smallest units using the filler according to the invention.
- a further special embodiment of the invention is characterized in that all fuel channels provided in the filler are designed in such a way that they have a low flow resistance. This ensures that the pressure loss through the filler is kept as low as possible.
- a further special embodiment of the invention is characterized in that the inlet of the connecting line in the pump housing is funnel-shaped. This keeps the pressure loss low.
- Another special embodiment of the invention is characterized in that two deflection channels are provided on opposite sides of the filler. This provides the advantage that the filler can be connected on two opposite sides of the pump housing.
- a further special embodiment of the invention is characterized in that in the surface of the filler facing the pump housing in the installed state of the filler, a plurality of chambers open at the bottom are formed are.
- the subdivision of the underside of the filler into a multiplicity of chambers ensures that the size of the air volumes which may be enclosed in the cavity is reduced to a harmless value.
- FIG 1 is a perspective view of a Biharmonic Stunas invention
- FIG. 2 shows a rear view of the filling piece from FIG. 1;
- FIG. 3 is a bottom view of the filler from FIG. 1.
- the filler shown in perspective in Figure 1 is received in a cavity which is between the top of the pump housing and the bottom of the
- Control unit housing an injection pump according to the invention is formed.
- a fuel inlet opens into the cavity, through which fuel flows out of a
- Fuel tank gets into the cavity.
- the fuel can either be conveyed into the cavity with the aid of a prefeed pump, or can be drawn in solely through the feed pump of the injection pump.
- a connecting line leads from the cavity to the conveyor device
- the opening for the connecting line is
- a fuel flow flows from the fuel inlet into the intermediate space. is formed between the bottom of the control unit housing and the top of the filler.
- the fuel develops its cooling effect in this space.
- the fuel passes through the inlet tulip 18 and the connecting pipe 19 to the connecting line (not shown) to the delivery device of the injection pump.
- the inventive design of the filler piece in such a way that the fuel is sucked out via the highest point by means of an inlet tulip or at least sucked off via the inlet tulip or at least can only flow off via the inlet tulip, ensures that the cavity at least up to the top 1 of the filler is filled.
