Claims

[Scope of utility model registration request]

A cylindrical bypass element and a full flow element are disposed coaxially within a cylindrical casing, and the lubricated oil supplied to the outer peripheral sides of the bypass element and the full flow element is filtered by passing through each of the elements. In the oil filter, the oil after filtration is taken out through a bypass passage and a full flow passage which communicate with the inner circumferential side of each element separately. a central hole facing the circumferential side, an inlet hole communicating with the outer circumferential side of each element around the center hole of the base plate, an inlet port communicating with the inlet hole on the outside of the base plate; An integrated base block is provided, each having a bypass outlet port forming an outlet of the bypass passage and a full flow outlet port forming an outlet of the full flow passage, and a large diameter portion integrally protruding from the base block is connected to the base plate. A small diameter part is screwed into the central hole of the casing and integrally protrudes from the tip of the large diameter part, and the small diameter part is disposed along the axis of the casing, and the tip thereof is communicated with the inner peripheral side of the full flow element. Fits oil-tightly into the proximal end of the shaft tube, forms the full flow passage along the axis of the large diameter part and the small diameter part, and defines the bypass passage in the large diameter part on the side of the full flow passage. An oil filter characterized by the following:
