Abstract

PURPOSE:To enable an oil filter to be arranged with good mounting and removal workability further with good space efficiency, by introducing lubricating oil, fed from an oil pump, to the oil filter from a connection port, opened to the external surface of an engine main unit, through an outer arranged pipe. CONSTITUTION:Lubricating oil, fed from an oil pump 9, passes through an oil path 10 in an engine main unit 1, and an engine introduces the lubricating oil to a mounting base 14 of an oil filter 12 from a connection port 11, formed on an external surface, through an outer arranged pipe 13 connected with said connection port 11. Accordingly, the lubricating oil can be introduced to the external surface of the engine main unit 1 and the oil filter 12 arranged in a position separated from the external surface. Consequently, the oil filter 12 can be arranged with good mounting and removal workability further with good space efficiency around the engine.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention mainly relates to an oil filter device for an engine mounted on a vehicle.

(Prior Art) Conventional oil filters are generally mounted on a mounting base fixed to an engine body, which has a connection port connected to an oil pump via an oil passage within the engine body.

(Problems to be Solved by the Invention) In the above-mentioned conventional system, the mounting base and therefore the oil filter are located near the oil pump on the outer surface of the engine body due to reasons such as oil passage machining. However, there are cases where it is difficult to place the oil filter in an efficient manner in the engine compartment while making it easy to install and remove the oil filter. Its purpose is to provide.

(Problem t - Means for Solving) In order to achieve the above object, the present invention provides a lubricating oil connection port = 2IA port connected to the oil pump via an oil passage inside the body on the outer surface of the engine body, (Embodiment) An oil filter is disposed on the outer surface of the engine body or at a suitable location spaced from the engine body, and lubricating oil is introduced to the oil filter through an external pipe connected to the connection port. The invention will now be described with reference to illustrated embodiments.

In the drawing, IJ is formed integrally with the crankcase (2a) at the bottom, and then the cylinder block (2) and this block (21).
) shows an engine body consisting of a cylinder head (3) disposed in the upper part, and an intake/exhaust valve (4) and a camshaft 7)+51 are disposed on the cylinder head (3); The pulley at the end of the crankcase (2 &) and the pulley at the end of the crankshaft 7) + 61 of the crankcase (2 &) are connected so that the engine is driven by the timing belt (7) and the engine t-W of accomplished.

In the drawing, (8) shows the main shaft case placed on the opposite side of the engine body (1317) (IE timing bell) (7).
) side and 111? f! An oil pump (9) for oil supply is arranged coaxially with the crankshaft +63, and the oil passage a1 connected to the oil pump (9) is connected to the peripheral wall of the crank case (2 holes) of the engine body (1). The shaft is drilled in the axial direction of the crankshaft (6).

According to the present invention, the oil pump (9) is connected to the outer surface of the engine body +II through the oil passage αlt- in the engine body +13.

In this case, as clearly shown in FIGS. 5 and 4, both pipes 0α3t and the engine body (13 mount brackets αD may be routed through the at- These pipes 13α4 are advantageously protected by the bracket (17).

In the above embodiment, the oil filter α2 is connected to the oil filter α2 using two external A4 pipes (13<131 t-), but each lubricant is directly connected to the outlet side of the mounting base α2 on the engine body +11. It is also possible to omit the outer pipe α3Jt on the outflow side by forming a # oil passage connected to the location.

(Function) Lubricating oil from the oil pump (9) is guided to the oil filter @ through the external pipe α3t formed on the outer surface of the engine body (1) and connected to it from the nine connection port αυ, and is therefore guided to the engine body. Self-lubricating oil is introduced to the oil filter α2 placed on the outer surface of (1) or at a suitable location spaced from the oil filter α2 via an outer pipe α31.

(Effects of the Invention) According to the present invention, the lubrication from the oil pump is led from the connection port opened on the outer surface of the engine body to the oil filter via the external pipe connected thereto. The opening has the effect of making it easy to install and remove the oil filter on the outer surface of the engine body and other places between the engine body and the oil filter in a space-efficient manner.
