Definitions

  • the invention relates to a pressure control arrangement with the features of the preamble of patent claim 1
  • the return flow from the injection pump has already been used as the driving jet for the suction jet pump.However, the aim is to dispense with a return line for cost reasons and to reduce possible leaks (compliance with emission regulations) really consumed
  • the filter cartridge or the filter housing is simply connected downstream of the pump and performs the pressure limitation and fine filtering of the fuel flow in a dual function
  • a particularly simple and quick installation can be achieved if all three connections are arranged on the same side of the filter housing, because it is then possible, for example, to first fasten the filter housing and then to establish the line connections on a fixed base
  • the pressure regulator is expediently arranged on a side of the housing facing away from the connections, so that there is sufficient installation space for its components on the one hand and the connections on the other hand. It is also advantageous if the pressure regulator is arranged downstream of the filter insert The long-term increasing throttle resistance of the filter insert has so no influence on the switching behavior of the pressure regulator. Furthermore, no unfiltered fuel gets into the regulating circuit. A particularly compact design occurs when the regulating line is arranged coaxially with the filter
  • the common housing will preferably consist of sheet metal and be sealed on both sides with a cover, for example by flanging.
  • a mechanical nut or the like can be provided in a known manner to mechanically fix the unit.
  • the single figure shows schematically a cross section through an inventive
  • a hollow cylindrical filter insert 2 is provided via an inlet 3 with an inlet connection 4, fuel is pumped into the housing 1 by a pump (not shown). This flows from the outer jacket surface of the filter insert 2 into its interior 5 and is thereby mechanically freed from impurities Filter insert 2, the fuel flows through a flow 6 to the consumer (also not shown). It flows through a flow connection 7, to which a flow line, not shown, is to be connected already filtered fuel is supplied At the pressure regulator input there is the flow pressure to be passed on to the consumer, which is approx. 3 500 hPa (3.5 bar).
  • the pressure regulator 9 includes a valve body 10 and a membrane 1 1 firmly connected to it Preliminary applied flat pressure, on the other hand, a compression spring 12 is arranged, which biases the valve body 10 against its valve seat 13, the latter being formed by the edge of an inlet of a regulating channel 14
  • the pretension of the compression spring 12, together with the pressurized surface of the membrane 11, defines the switching threshold of the pressure regulator 9.
  • the housing is preferably made of sheet metal and is sealed at both ends with covers 16, 17.
  • the (left) cover 16 comprises the three connections of the pressure regulating arrangement, while the (right) cover 17 covers the pressure regulator 9 together with the spring 12
  • all three connections of the common housing can preferably be arranged coaxially with respect to one another, as is already known in the case of normal fuel filters with only two connections completely sealable and beyond the connection piece separately connectable channels to be provided on the outer wall of the outer channel of the common housing is then z To provide threads that can be screwed into a corresponding counterpart on said connector.
  • Such a pressure control arrangement could thus also be connected or replaced very quickly and with the lowest probability of error.

Abstract

L'invention concerne un dispositif de régulation de pression placé entre une pompe et un consommateur, notamment entre une pompe de carburant et un moteur à combustion interne. En cas de dépassement d'une pression déterminée, une quantité de régulation est dérivée par la conduite de refoulement de la pompe et acheminée jusqu'à un réservoir. Selon l'invention, le régulateur de pression (9), placé à proximité de la conduite de régulation (14), est composé d'une unité de montage dotée d'un filtre (2). De préférence, les trois raccords (raccord d'alimentation (4), raccord de refoulement (7) et raccord de régulation (15)) sont placés du même côté d'un boîtier commun (1). Dans un mode de réalisation particulièrement avantageux, les trois raccords ont une disposition relative coaxiale de telle façon qu'en cas d'utilisation d'un raccord correspondant, toute erreur de montage soit exclue.
