Blow-by gas filtering assembly with supporting module

Abstract

A blow-by gas filtering assembly is connected to an engine system of a vehicle in a fluid form to receive blow-by gas and filter out suspended particles contained in the blow-by gas. The blow-by gas filtering assembly comprises a main body, a filter element, a driving assembly and a supporting module, wherein the main body comprises a filter chamber and a gas outlet formed in an axis; the blow-by gas can radially penetrate through the filter element from outside to inside, and the filter element comprises a central cavity; the driving assembly is partially contained and supported on the main body and is operably connected to the filter element to drive the filter element to rotate; the supporting module supports the filter element on the main body and comprises i) a bearing element and ii) a hollow tubular element; the bearing element comprises an outer fifth wheel engaged with the edge of the gas outlet in a sealed mode and an inner fifth wheel defining a gas outlet passage, and the filtered blow-by gas flows through the gas outlet passage; and the hollow tubular element defines an outlet pipeline for the filtered blow-by gas, and comprises a bearing end operably connected to the inner fifth wheel and a supporting part extending from the bearing end in the central cavity, so that the filter element is mounted on the supporting part.

Description

technical field [0001] The invention relates to a blow-by gas filter assembly. [0002] In particular, the blow-by filter assembly of the present invention may be fluidly connected to the crankcase ventilation circuit of an internal combustion engine system inside a vehicle to receive and filter blow-by gases (from the crankcase) such that the blow-by gases contained in the Suspended particles in the air are filtered out. [0003] Specifically, "blow-by gas" refers to oil vapor that is exhausted from a crankcase of an internal combustion engine during operation of the internal combustion engine. In particular, blow-by gases have a similar composition to exhaust gases and are produced by the combustion of an air / fuel mixture in a combustion chamber. Instead of reaching the exhaust circuit, these gases leak into the lower part of the crankcase, passing along the cylinders and carrying carbon particles and oil droplets with them. In this paper, for simplicity, the blow-by gas ...
