Definitions

  • the invention relates to a vent valve according to the preamble of claim 1.
  • Breather valves are used for venting crankcases of internal combustion engines, which are formed from a housing with inlet and outlet ports.
  • the inlet connector is connected to the crankcase, while the outlet connector opens into the intake line of the internal combustion engine.
  • Equalization valves are provided for pressure equalization, which are arranged between the outlet connection and the suction line.
  • Baffles are provided in the vent valve to separate droplets from the oil mist. The separated oil is returned to the oil pan via a drain. Vent valves of this type have the decisive disadvantage that they can only separate the oil already in droplet form, the oil still in the vapor phase is not extracted.
  • the invention is based on the object of also separating off the oil still present in the vapor phase.
  • the oil vapor is condensed and separated in the liquid state.
  • the V-ribs which are arranged opposite the inlet connection, are used for the complete separation of oil droplets, which are returned to the oil pan via the drain below.
  • An advantageous development of the invention is characterized by the features of claim 2.
  • a Peltier element as a cooling device in connection with wire pins made of a material with high thermal conductivity, e.g. Copper, a wear-free device that is minimized in terms of construction is created, with which oil vapor can be condensed and subsequently separated in droplet form.
  • the vent valve consists of a housing 1 with an inlet connector 2 and an outlet connector 3.
  • the inlet connector 2 communicates with a crankcase, while the outlet connector 3 opens into an intake line of the internal combustion engine with the interposition of a compensating valve.
  • the vent valve has baffles 4, which are designed here in the form of wire pins.
  • the wire pins are connected to a base plate 5, which seals the housing 1 in a gas-tight manner at its periphery by means of a circumferential seal 6.
  • the wire pins and the base plate 5 are preferably made of a material with high thermal conductivity, for example in copper.
  • a cooling device 7 in the form of a Peltier element is connected to the base plate 6 with its cold side in a heat-conducting manner.
  • the warm side of the Peltier element 7 carries cooling fins 8 to dissipate the heat to the surroundings.
  • the housing 1 Opposite the inlet connector 2, the housing 1 has V-ribs 9 in order to completely separate the oil droplets formed on the wire pins by condensation of the oil vapor.
  • the separated oil is returned via an outlet 10 to an oil pan in the internal combustion engine.
  • the gas stream cleaned from oil leaves the housing 1 via the outlet port 3 and is returned to an intake line of the internal combustion engine after passing through a compensating valve.
  • the Peltier element therefore separates not only the oil that is in the liquid state, but also the oil that is still in the vapor phase.
  • the Peltier element allows wear-free condensation of the oil vapors in the gas flow with minimal construction effort.
  • another cooling device can of course also be provided, for example integration into a circuit of an air conditioning system in buses or the like.
