Claim 4

Apparatus according to claim 1, wherein the delivery piping from the pump is connected through changing-over branch piping and a by-pass valve through the by-pass piping and discharge branch piping to the storage reservoir and thence to the outlet piping from the storage reservoir.

Claim 5

In an apparatus for the vortical separation of liquid having different densities with automatic delivery, said apparatus having a pump, a filter, a vortex separator, a cylindrical housing for the vortex separator, discharge piping tangentially attached to the housing and to the pump, the reservoir being closed in the lower part thereof with a conical bottom and with a vortex chamber provided with tangentially attached feed piping with a suction basket and a run-back closure, the improvement wherein a conical insertion piece is disposed in the cylindrical housing for the vortex separator coaxially thereof, the upper part of the cylindrical housing of the vortex separator is closed by an upwardly converging frusto-conical housing part above which there is attached the housing for a filter, the two housings being coaxial, the housing for the filter being closed at the bottom thereof by a slanting bottom and in the upper part thereof by an upper sealing joint, the upper housing part for the filter being closed by a upwardly converging cover coaxial thereof, delivery piping, changing-over branch piping, changing-over closure and inlet piping being tangentially attached to the lower part of the housing for the filter and being connected to the pump and to the upper housing for the filter, discharge piping tangentially attached to the upper part of the housing for the filter and connected through a discharge valve through and through discharge branch piping to a storage reservoir, discharge piping for said reservoir, a discharge coupling being connected to the housing for the filter beneath the slanting bottom of the housing, such coupling being ended by an electromagnetic valve which is connected by an electric circuit with an upper fluid level detector and by a further interconnecting circuit with a lower liquid level detector, the electromagnetic valve being further connected with the electric motor for the pump by a still further electric circuit.

Claim 6
