ルタ。 A cup-shaped case, a cover plate fixed to cover the opening of the case, an oil outlet hole that also serves as a cylindrical mounting hole formed in the center of the cover plate, and an oil outlet hole of the cover plate. A plurality of oil inlet holes are formed around the outlet hole, and the oil inlet holes are formed in a thick cylindrical shape and are built concentrically in the case, and the outer circumference side communicates with the oil inlet hole, and the inner circumference side communicates with the oil outlet hole. a filter element communicating with the hole; and an inlet-side check valve formed by applying an elastic valve piece to the inner surface of the oil inlet hole;
an outlet side check valve installed near the oil outlet hole in the inner cylinder portion of the filter element;
This outlet side check valve is equipped with a fixed cylinder having a pressure guiding hole on the ceiling surface and an oil passage hole on the circumferential surface, and is slidably installed inscribed in this fixed cylinder, and the above pressure guiding hole is inserted from the inside. It is composed of a slide cylinder having a ceiling surface to be closed and an oil passage hole on the circumferential surface, and a spring that biases the slide cylinder in a direction opposite to the direction of pressure from the pressure guiding hole,
When no pressure is applied to the slide cylinder from the pressure guiding hole, the oil passage hole of this slide cylinder and the oil passage hole of the fixed cylinder do not match, and when the slide cylinder slides under the above pressure, both of the oil An oil filter characterized in that the through holes are configured to match.
