The upper chamber and the basket are separated by sealing means associated with a device accommodated in the said chamber for the delivery of water under pressure to the said basket. The said sealing means, in a phase of increasing pressure in the chamber, exercise a pressure on the said basket, sealing it in position, and the said device delivers water under pressure to the said filter while, in a phase of decreasing pressure in the said chamber, the said device interrupts the delivery of water to the said filter and the said means interrupt the pressure on the said basket, permitting the removal thereof from the associated housing when necessary.
