Description

A kind of end cover structure for filter cleaner

technical field:

The present invention really relates generally to filter cleaner technical field, particularly relates to a kind of end cover structure for filter cleaner.

background technique:

Filter cleaner includes air-strainer, oil filter and fuel filter.

Air-strainer is arranged in engine aspirating system, the assembly that it is made up of the filter component of one or several clean air.Its Main Function is that filtering will enter objectionable impurities in the air of cylinder, to reduce the premature wear of cylinder, piston, piston ring, valve and valve seat.

Oil filter is arranged in engine lubrication system.Its upstream is oil pump, and downstream is each component needing in motor to lubricate.Its effect carries out filtering to from objectionable impurities in the machine oil of oil sump, with the kinematic pair such as engine oil supplying bent axle, connecting rod, camshaft, pressurized machine, piston ring of cleaning, plays lubrication, cooling, cleaning action, thus extend the life-span of these component.

Fuel filter is connected on the pipeline between fuel pump and throttle valve body filler opening.The effect of fuel filter, is solid sundries removings such as the iron oxide be contained in fuel oil, dust, prevents oil-fired system from blocking.

In filter cleaner, the structure of each parts will have influence on the usability of filter cleaner.Such as the end cover structure of filter cleaner.
