Problems solved by technology

For an engine with a turbocharger, its lubrication system has more stringent requirements, such as the oil pressure range when the engine is running, and the oil temperature rise limit of the turbocharger lubrication system when the engine is shut down, etc., but currently Conventional lubrication systems are difficult to meet the above requirements

Embodiment Construction

[0007] Such as figure 1 As shown, a pressure-stabilizing filter, the filter 70 is provided with a filter chamber 74 filled with a filter element 71, and a pressure-regulating chamber 75 is provided beside the filter chamber 74 to adjust the pressure.

[0008] The engine oil in the lubricating system is filtered through the filter element 71, and at the same time the pressure fluctuation is reduced under the action of the pressure stabilizing chamber 75, so as to achieve the purpose of stabilizing and storing pressure.

[0009] Such as figure 1 As shown, the filter 70 is columnar, and the middle part of the column is set as a plenum chamber 75, and the filter chamber 74 is arranged outside the plenum chamber 75, and one side of the filter chamber 74 is connected to the input of the filter 70. One end is communicated, and the other side is communicated with the output end of filter 70.

[0010] The above arrangement can properly extend the filtering path of the filter chamber ...

Abstract

The invention belongs to the technical field of automobile engine lubrication, particularly relates to a pressure stabilizing filter. The filter is internally provided with a filtering chamber which is filled with filter elements; and the side of the filtering chamber is provided with a pressure stabilizing chamber for adjusting pressure. In the technical scheme, the filter is internally with the pressure stabilizing chamber which plays a role of stabilizing pressure and storing pressure in a whole lubricating system, and the pressure stabilizing chamber can adjust the pressure of the whole lubricating system, reduce the pressure peak value in the lubricating system and continuously supply oil for a turbocharger when an engine shut down suddenly, thereby achieving the goal of protecting the turbocharger.

Description

technical field [0001] The invention belongs to the technical field of automobile engine lubrication, and in particular relates to a pressure stabilizing filter. Background technique [0002] With the increasingly stringent emission regulations, turbochargers have become the basic configuration of many engines, especially diesel engines, and turbochargers are more widely used. For an engine with a turbocharger, its lubrication system has more stringent requirements, such as the oil pressure range when the engine is running, and the oil temperature rise limit of the turbocharger lubrication system when the engine is shut down, etc., but currently Conventional lubrication systems are difficult to meet the above requirements. Contents of the invention [0003] The purpose of the present invention is to provide a pressure stabilizing filter, which has a simple structure, can protect the turbocharger under various working conditions, and helps the engine work stably and reliab...
