Definitions
- TECHNICAL FIELD This invention relates in general to a device for separating fluids of different density.
- Burnt gases are known to return to the lower chambers of internal combustion engine cylinders because of seepage past the piston rings or because of imperfect connections. These gases are generally fed to the engine intake manifold, which then feeds them to the cylinders for combustion via a suitable conduit.
- Separator devices which separate said burnt gases from the oil particles which they entrain when coming into contact with the oil in the engine oil sump.
- the known devices comprise a casing provided with an entry conduit for the gas and oil mixture and an exit conduit for the gas, a separator, for example of the coalescence type comprising a filtering baffle, being interposed between said entry and exit conduits.
- the filtering baffle substantially divides the interior of the device into two separate chambers.
- a conduit is present in the upstream chamber for discharging the oil which separates from the mixture and collects by gravity on the bottom of the upstream chamber.
- the object of the present invention is to overcome the drawbacks of the known art within the framework of a simple, rational and low-cost solution.
- the invention attains said object by virtue of the characteristics defined in the claims.
- a separator device comprising an outer casing provided with an entry conduit for a mixture of fluids of different density, and an exit conduit for the fluid of lesser density, said conduits being separated by a filtering means which defines an upstream chamber to which said entry conduit leads, and a downstream chamber from which said exit conduit leaves, a valve member being provided which when opened connects said chambers together, a conduit for discharging the fluid of greater density being associated with one of said chambers.
- said valve member is positioned in proximity to the bottom of said casing where the fluid of greater density collects.
- the valve member comprises a umbrella valve which is opened by the pressure exerted on it by the fluid of greater density which has collected on the bottom of said casing.
- the conduit for discharging the fluid of greater density is positioned in the chamber to which said mixture entry conduit also leads.
- valve member can be associated either with the filtering means or with the outer casing of the separator device.
- said filtering means can be of coalescence, labyrinth, cyclone or centrifugal type.
- Figure 1 is a section through the device of the invention.
- Figure 2 is an enlarged view of a detail of the invention.
- FIG. 1 shows the device 1 , which in the illustrated embodiment is used to separate a mixture of engine burnt gases and oil and is hence intended to be inserted into the circuit which connects the burnt gas and oil mixture discharge to the engine fuel intake manifold (not shown).
- the device 1 comprises an outer casing 2 having an entry conduit 3 through which said burnt gas and oil mixture enters the device, and an exit conduit 4 through which the burnt gases alone leave.
- the filtering means 5 separates the casing interior into two separate chambers, namely a chamber 6 upstream of the filtering means, to which said entry conduit 3 leads, and a chamber 7 downstream of the filtering means 5, from which said exit conduit 4 leaves.
- the filtering means 5 is provided with two endpieces 50 and 51 by which it is fitted to the casing 2.
- a valve member 9 ( Figure 2) comprising a umbrella valve 10 which opens by the pressure which the oil collected on the bottom of the chamber 7 exerts on the annular wall 100 of the valve 10 by way of the holes 11 present in the endpiece 51.
- oil separated by the filtering means collects on the bottom of the chamber 6, whereas the oil which falls onto the bottom of the chamber 7 is discharged through the conduit 8.
- the pressure which it exerts on the valve 10 is such that the valve opens and by passing through the holes 11 the oil flows from the chamber 7 to the chamber 6, and from there is discharged through the discharge conduit 8.
