  • Patent number: 6890434
    Abstract: A backflushing filter for filtering oil includes filter candles 22 which are open at both ends 24, 34 and disposed around a rotary shaft 1 in a filter housing. A cleaning device is moved in conjunction with the rotary shaft and includes upper and lower flushing cocks communicating with an outflow valve via the shaft for cleaning the candles during a backflushing operation. The upper flushing cock 27 is offset by an angle in the direction of rotation in relation to the lower flushing cock 37. A lower closure element 38 moves in conjunction with the upper flushing cock at the opposite end of a filter candle(s) selected for backflushing. Likewise, an upper closure element is associated with the lower flushing cock. The candles can be reverse-flushed in opposite directions and at different times by the flushing cocks and closure elements. The flushing cocks and closure elements are moved inside annular deflection hoods 60, 70.

  • Publication number: 20030136715
    Abstract: This invention relates to a backflushing filter, particularly for filtering lubricating oil. Filter candles 22 which are open at both ends 24, 34 are disposed around a rotary shaft 1 in the filter housing 11, 12, the interior space of which filter candles can be acted upon in filtration operation by a sludge which flows into the backflushing filter 10. A cleaning device is moved in conjunction by means of the rotary shaft 1, and comprises an upper flushing cock 27 and a lower flushing cock, which communicate with an outflow valve via the rotary shaft 1, for cleaning the filter candles 22′ during a backflushing operation. The upper flushing cock 27 is offset by an angle in the direction of rotation in relation to the lower flushing cock 37.

  • Patent number: 6006431
    Abstract: To produce a two-part valve housing inexpensively it is proposed to produce from a sleeve-shaped blank (20) by internal high-pressure forming an intermediate product (10) which corresponds to the first housing part in a section lying on one side of a separating surface (T) and to the second housing part in a section lying on the other side of the separating surface (T). Connection sections (24, 32), adjacent to the separating surface, of the intermediate product (20) have different diameters so that cooperating threads by means of which the housing parts are screwed together can be produced on them.
