Filtration system self cleaning mechanism

A method for regulating a linear displacement of a suction scanner of a self-cleaning filtration system, the method comprising:

• providing a regulative flow-restriction-barrier amidst a body of a regulative-fluid whereby regulative-fluid from opposite sides of the flow-restriction-barrier is communicable only through a regulative flow-path extending across the flow-restriction-barrier;
• associating a linear displaceable body of the suction scanner with a regulative-fluid compression element linearly comoving with the suction scanner;
• and
• enforcing regulative-fluid of said body of regulative-fluid to flow through the regulative flow-restriction-barrier in a first direction when the suction scanner is linearly displaced from an initial position to a second position, and in direction opposite to the first direction when the suction scanner returns from the second position to the initial position.

A filtration system comprising:

• a raw fluid inlet,
• a filtered fluid outlet,
• a filtration chamber,
• a filter element positioned in said filtration chamber between said raw fluid inlet and said filtered fluid outlet, and
• a suction scanner for cleaning said filter element upon activation of a cleaning session, the suction scanner that is rotatable about a longitudinal axis and is linearly movable along the longitudinal axis between a first and a second predetermined positions;
• and
• a linear displacement regulator that is configured to automatically regulate a linear motion of said suction scanner between the first and second positions, the linear displacement regulator comprises:
• a regulative-fluid compartment in liquid communication with a flow-restriction-barrier;
• and
• a regulative-fluid compression element linearly comoving with the suction scanner and configured to enforce a regulative-fluid filled in the regulative-fluid compartment to flow through the regulative flow-restriction-barrier.
