Abstract

Invention m. used in automotive engine building. The purpose of the invention is to simplify the filter. On the outer surface of the housing 1 there is a conical groove 3 for the sealing ring 4. In the center of the bottom 2 of the housing there is a threaded hole 5, and on the periphery - an opening 10, which connects the inner and outer cavities 8 and 9 respectively. A filtering element 6 and an overflow valve 7 are placed in the cavity 8. In the plane of the axis of the hole 10 on the outer side of the housing, risk 11 is made, parallel to the axis of the filter. Due to the tapering of the groove 3, it is possible to install the filter with a riser 11 upwards with simultaneous compaction, since body can be adjusted by sealing the ring. 4. Communication of cavity 8 with the engine lubrication system at the top point ensures that the filter is full of oil when the engine is turned off. 1 The K-qi filter is simplified by eliminating the anti-drain valve. 1 il.

FIELD OF THE INVENTION The invention relates to automotive engine construction, in particular to the purification of oil in internal combustion engines.

The purpose of the invention is a filter (filter design).

The drawing shows the proposed filter, a longitudinal section.

The filter includes a housing 1 with 2 days, on which there is a tapered groove 3 under the sealing ring 4 and a threaded hole 5 located in the center of the bottom 1, filtering element 6, overflow valve 7 and the internal cavity 8. In addition, from the outside the bottom is made external cavity 9, communicated with the internal cavity 8 hole

10, in the O-plane of which, on the outer side of the housing 1, the risk M is parallel to the filter axis.

The filter works as follows

The sealing ring 4 is installed in the conical groove 3, in the cutout of which the filter with its threaded hole 5, pacnojiokennbiM in the bottom 2, is screwed onto the fitting of the oil system located on the cylinder block (not shown) so that the risk

11, formed on the outer side of the housing 1, is in the upper position. The installation of the filtering with the riser 11 upwards while ensuring sealing is carried out due to the conicity of the groove 3, since

in this case, the door of the housing 1 can be made 1/4 - 1/6 of the circumference by sealing the ring 4 in the corner recess.

When the engine is operating, the grease oil from the lubrication system enters the external cavity 9 and then through the opening 10 into the internal cavity 8, and the clean oil, having passed through the filter element 6, enters the lubrication system. With an increase in the resistance of the filter element 6, the oil enters the lubrication system, mine, through the bypass valve 7

When the engine is turned off, the filter remains filled with oil due to the fact that the internal cavity 8 communicates with the engine lubrication system at the top point, which is ensured by proper orientation during its installation,

I

Thus, the proposed technical solution allows, while maintaining the same reliability of the lubrication system (when starting the engine, the oil immediately enters the bearing assemblies to simplify the design of the filter, except for the anti-drain valve.
