Abstract

A drain valve structure of an oil filter is provided to reduce manufacturing cost and improve productivity by forming a drain valve using two parts. A drain valve structure of an oil filter comprises an oil filter housing(11) having an oil inlet, an oil outlet and an oil discharge tube(80), a cover(12) and an oil filter element(13). The cover is screwed to an upper part of the oil filter housing to prevent oil leak. An upper cap(14) of the oil filter element is coupled to the cover. A drain valve including a guide(16) and a support pin(17) is coupled to a lower end of a lower cap(15). The guide and the support pin are coupled to the oil filter housing so that the oil filter element is supported by the support pin.

<Explanation of symbols for main parts of the drawings>

10: conventional split drain valve 11: oil filter housing

12: cover 13: filtration element

14: upper cap 15: lower cap

16: guide 17: support pin

20: drain valve in oil filter unit 30: seating part

40: protrusion 50: primary spring

60: secondary spring 70: sealing seat

80: oil drain pipe

The present invention provides an oil pan re-inflow passage so that engine oil remaining in the engine oil filter when the replaceable oil filtration element 13 in the engine oil filter of the vehicle is replaced can be easily introduced into the oil pan through the oil drain pipe 80. It relates to a drain valve structure in the oil filter to precisely perform the opening and closing function of the.

In the case of the drain valve structure of the existing engine oil filter unit (Attachment 1), when the replaceable filtration element 13 is inserted into the oil filter housing 11, the drain valve 10 is connected to the lower portion of the oil filtration element 13. Pressed by the cap 15, the protrusion 40, the seating portion 30, the primary and secondary spring 50, 60 is in contact with the sealing seat 60, the discharge inlet is blocked, the oil filter housing ( 11) when the cover is opened, the primary and secondary springs (50) and (60), which are pressed, push the seating portion (30) and the protrusion (40), and the protrusion (40) removes the inserted exchangeable oil filtration element. At the same time, the oil remaining in the inside is pushed out by the protrusion portion is designed to be re-introduced into the oil pan through the oil drain pipe (80).

However, the drain valve of such a structure has a complicated structure such as a protrusion, a seating part, a primary and a secondary spring, and is composed of four or more parts, thereby reducing the productivity and the increase in manufacturing cost due to increased labor. I have it.

An object of the present invention for solving the problems as described above is an oil pan so that the oil remaining in the oil filter during the replacement operation of the replaceable oil filtration element 13 is easily re-introduced into the oil pan through the oil drain pipe (80) By simplifying the drain valve 20 for precisely performing the opening and closing function of the reflow passage into two parts, the number of parts constituting the engine oil filter is reduced compared to the existing drain valve 10, and changed into a simple structure. The purpose is to construct an oil filter drain valve that can increase productivity and reduce the cost of parts.

Drain valve 20 in the oil filter unit of the present invention for achieving the above object is to fasten the guide 16 and the support pin 17 to the oil filter housing, and support the oil filtration element with the support pin when mounting the interchangeable oil filtration element The structure is characterized by.

In addition, when the oil filter element 13 is separated from the oil filter housing 11, the drain valve 20 in the oil filter device of the present invention has a structure such as a spring that does not require a structure by using a gravity load.

An oil filtration element according to the present invention and a drain valve in an oil filter will be described below with reference to the accompanying drawings.

3 is a cross-sectional view showing the oil filtration element and the drain valve in the oil filter unit.

4 is a cross-sectional view of the drain valve structure in the oil filter unit when the oil filtration element is combined.

Figure 5 is a cross-sectional view of the drain valve structure in the oil filter when the oil filtration element is separated from the oil filtration element housing in the structure according to the present invention.

As shown in FIG. 3, the oil filter having the oil filtration element and the drain valve structure is screwed to an oil filter housing 11 having an oil inlet, an oil outlet, and an oil outlet pipe 80, and an upper portion of the oil filter housing 11 to drain the oil. The cover 12 and the oil filtration element 13 for removing foreign matter contained in the oil filter,

The upper cap 14 of the oil filtration element 13 is coupled to the oil filter cover part 12, and during the replacement operation of the oil filtration element 13 at the bottom of the lower cap 15 of the oil filtration element 13. The oil remaining in the oil filter is guide (16) and the support pin-type drain valve (20) to precisely perform the opening and closing function of the oil pan reflow passage to facilitate the inflow into the oil pan through the oil drain pipe (80). Are constructed in combination

The drain valve 20 in the oil filter unit is configured to fasten the guide 16 and the support pin 17 to the oil filter housing 11 and support the oil filtration element with the support pin when the exchangeable oil filtration element is installed. It is.

According to the present invention configured as described above, the structure of the drain valve 20 in the oil filter is simplified to two parts, which reduces the number of parts constituting the engine oil filter compared to the conventional drain valve 10, and the simplified structure. The change has the effect of reducing production man-hours and improving productivity and reducing part costs.

Claims (2)

As shown in the drawing, the oil pan reflow passage can be precisely opened and closed so that the oil remaining in the oil filter when the oil filtration element 13 is replaced can be easily introduced into the oil pan through the oil drain pipe 80. Drain valve in the oil filter unit. The oil filter element according to claim 1, wherein the drain valve 20 in the oil filter unit fastens the guide 16 and the support pin 17 to the oil filter housing 11, and supports the oil filtration element when the exchangeable oil filtration element is mounted. It consists of a supporting structure, Drain valve structure in the oil filter, characterized in that the productivity and parts cost is reduced by reducing the number of parts constituting the engine oil filter and simplifying the structure compared to the conventional separate drain valve (10).
