摘要： 7 A filter including a housing (2) having an inlet (4) connectable to an upstream pipe, and an outlet (6) connectable to a downstream pipe; and a stack of discs (20) disposed within the housing (2) for separating solid particles from a fluid flowing between the discs (20) from the upstream side of said stack to the downstream side thereof. The filter discs (20) have a large surface area of their side faces formed with grooves and a spacer member (22) interposed between each pair of adjacent filter discs (20), the spacer members (20) having surfaces contacting only a portion of the grooved faces of the filter discs (20) on the upstream side of the stack not contacted by the spacer members (22) to thereby form compartments (24) on the upstream side of the stack for accumulation of solid particles which settle in the grooves, edge filtering passageways along the upstream edges of the spacer members (22) in contact with the grooved faces of the filter discs (20), which passageways define the size of particles separated by the filter and further filtering passageways of large surface area in the compartments (24), these latter passageways extending between the particles settling in the grooves in the compartments (24) and through the grooves to the downstream side of the stack.

摘要： A filter that comprises a stack of filter discs within its housing with the side faces of the discs formed with surfaces effective to filter the fluid flowing between them from the housing inlet to the outlet, according to one embodiment of the present invention, at least some of the discs being formed with a serrated edge at the upstream side of the stack facing the housing inlet, which serrated edges are effective to increase the upstream filter surface and also to form pockets for receiving dirt particles. According to another embodiment of the present invention, the thickness of each of the filter discs is smaller at its upstream side than at its downstream side, and/or the depth of their grooves is larger at the upstream side than at the downstream side, such that the upstream side of the stack of filter discs is formed with pockets between adjacent discs, in addition to said grooves, for receiving and holding foreign particles separated from the fluid.
