Definitions

  • the invention relates to a device for supplying an internal combustion engine with fuel from a storage container according to the preamble of claim 1.
  • Such a device is known from DE 42 31 731 A1.
  • This device has a feed pump arranged in the storage container, which can be inserted through an opening in the storage container.
  • the opening in the storage container can be closed by means of a closure part on which a pressure regulator is arranged.
  • the pressure regulator has a pressure chamber which has a connection to the pressure side of the feed pump, to the internal combustion engine and to a relief line.
  • the connection of the pressure chamber to the relief line is controlled by a spring-loaded closing element which interacts with a seat and releases the connection to the relief line when a certain pressure in the pressure chamber is exceeded.
  • the closure part has an inner body which is made smaller than the opening in the storage container.
  • the inner body is provided with an envelope that coexists with the inner body optionally closes the opening with the interposition of a sealing element.
  • Channels are formed in the inner body, which form the connections to the feed pump, to the internal combustion engine and to the relief line.
  • connecting pieces are inserted as separate parts, onto which lines for connection to the feed pump and the internal combustion engine can be attached.
  • the closing member of the pressure regulator is designed as a ball which interacts with a seat formed in the inner body of the closure part at a cross-sectional constriction of a channel. For a secure seal by the ball, the seat must be machined, which means a complex manufacture of the inner body of the closure part.
  • the inner body of the closure member having the seat must be made of metal in order to ensure sufficient durability of the seat.
  • the multi-part design of the closure part with the inner body and the casing necessitates a complex manufacture.
  • the sockets have to be inserted separately into the inner body. Overall, the design of the closure part in this known device is complex to manufacture and assemble, which should be avoided for economic reasons.
  • the device according to the invention for supplying an internal combustion engine with fuel from a storage container with the features according to claim 1 has the advantage that the closure part is of simple construction due to the one-piece body which closes the opening.
  • the pressure regulator is also simply designed with the membrane serving as a closing member and the front end serving as a seat of the connecting piece projecting into the recess. Through the elastic membrane provides a secure seal even when the seat is not machined.
