ABSTRACT:
A filter for filtering oil flowing through a fluid flow passage extending through the inside and outside of a plug forming part of a relief valve of a vane pump. The filter comprises a roll-shaped sheet formed of steel sheet spring and taking a generally cylindrical form. The roll-shaped sheet has overlapping first and second end sections, which are opposite to each other in a peripheral direction of the roll-shaped sheet. The roll-shaped sheet is located in the fluid flow passage and fitted on an outer peripheral surface of the cylindrical member. The roll-shaped sheet is formed with many through-holes having the size to allow the fluid to pass through the through-holes but trap particles for removal.
