Abstract:
The present invention is a filter mechanism provided in a pump or the like, and the purpose thereof is to provide a filter mechanism that can eliminate foreign matter adhering to the surface of a filter and thereby can prevent clogging of filters because of foreign matter. According to the present invention, an area toward the inside in the direction of the radius of the filter is linked to an intake opening ( 235 ) of the pump (for example, a trochoid pump ( 22 )) and, via the pump ( 22 ) to a pump ejection opening (trochoid pump ejection opening ( 215 )), and an area between a filter ( 5 ) and (an inside wall surface ( 3 i ) of) a first casing ( 3 ) is linked to a low-pressure ejection opening (discharge opening ( 237 )) for a working fluid.

Claim (Index 6):
A filter mechanism, comprising:\n a substantially cylindrical filter being fixed to a first casing so as to not move relative to the first casing and being accommodated within the first casing, the substantially cylindrical filter extending along a longitudinal direction; a space is formed between the filter and an inner wall surface of the first casing along a radial direction; and a movable blade is arranged in the space formed along the radial direction and is apart from an outer surface of the filter, wherein said movable blade is movable in a circumferential direction of the filter, and the blade is constructed so that a pressure of a working fluid is lowered in the region where the movable blade passes and a differential pressure is generated between a radially outer region relative to the filter and a radially inner region of the filter, a turbulent flow and vortex are generated behind the movable blade when the blade moves, and that foreign matters adhering on a radially outer surface of the filter are detached by the force generated by the differential pressure and the force generated by the turbulent flow and vortex, wherein the movable blade is substantially straight and extends to be parallel to a central axis of the first casing, wherein the moveable blade integrally extends along the longitudinal direction of substantially the entire length of the filter, and wherein a fluid inlet is connected to the space between the filter and an inner wall surface of the first casing and a fluid outlet is connected to an interior of the filter such that the working fluid passes from the radially outer region to the radially inner region of the filter and the radially inner region of the filter connects to an intake opening for the pump.
