Dual-purpose filter holder device

Abstract

The invention discloses a dual-purpose filter seat device. The dual-purpose filter seat device comprises a seat body and a transition plate, and the seat body is provided with an end portion structureconnected with a replaceable filter element type filter in a sealing mode; the transition plate is provided with a first end portion and a second end portion which are arranged oppositely; the firstend portion is adaptive to the end portion structure of the seat body, and the second end portion is adaptive to the connecting end of a screw-mounted type filter; and the transition plate is detachably and fixedly connected with the seat body through a threaded connecting piece. The dual-purpose filter seat device can match with the engine oil / fuel oil replaceable filter element type filter and can match with the engine oil / fuel oil crew-mounted type filter, the universality of the filter seat device is improved, the manufacturing cost of engines is reduced, and consumer use is facilitated.

Description

technical field [0001] The invention relates to the technical field of filter seat devices, in particular to a filter seat device that can be used not only with an engine oil / fuel replaceable element filter but also with an engine oil / fuel spin-on filter . Background technique [0002] The oil filter is located in the engine lubrication system, its upstream is the oil pump, and its downstream is the parts that need to be lubricated in the engine. Its function is to filter out harmful impurities in the engine oil from the oil pan, and supply the clean engine oil to the crankshaft, connecting rod, camshaft, supercharger, piston ring and other kinematic pairs to lubricate, cool and clean, thereby Extend the life of these components. [0003] The function of the fuel filter is to filter out harmful particles in the engine fuel system to protect the oil pump nozzle, cylinder liner, piston ring, etc., reduce wear and avoid clogging. Even if the fuel is clean after being precipi...

AI Technical Summary

Problems solved by technology

The second known filter seat can only be installed with a spin-on filter, and the filter cartridge and filter element of the spin-on filter cannot be disassembled, and can only be screwed on the mounting studs of the filter seat

If the user wants to replace the replaceable element filter with a spin-on filter, he needs to re-equip a filter seat. The filter seat has poor versatility, increases the manufacturing cost of the engine, and brings inconvenience to the user. inconvenient
