Problems solved by technology

A disadvantage of known spreading devices is that, even if a further non-return valve is present, the quantity of additive dispersed by known spreading devices is proportional to the pressure difference between the environment upstream and downstream of the filter element, whereby at times of high additive consumption, for example, e.g. in the event of sudden pressure peaks, especially at the end of the service life of the filter element
[0012] In order to reduce this effect, it is known to use controlled actuators to distribute the consumption of additives, but their use is particularly complicated and expensive

Embodiment 2

[0094] In embodiment 2, such as Figure 2-6 As shown (where the same reference numerals are used for the same parts), the filter group 10 includes an outer cover (generally designated as 20 ), which is composed of a substantially beaker-shaped main body 21, and the top of the main body 21 is closed by a cover 22, the cover 22 is, for example, circular and is detachably fixed on the beaker main body 21 with fixing screws or other blocking devices.

[0095] The cover 22 comprises an inlet 23 for the liquid to be filtered, for example constituted by an off-centre through-hole provided on the cover 22 , into which an inlet sleeve 231 is sealingly inserted.

[0096] The cover 22 also includes an outlet 24 for the liquid to be filtered, for example constituted by a through hole provided on the cover 22 and coaxial with the beaker main body 21 .

[0097] The filter element generally indicated at 30 is housed inside the housing 20 .

[0098]Said filter element 30 comprises a tubular...

Embodiment 3

[0152] In embodiment 3, such as Figure 7-11 As shown, the filter set 10 includes a housing (generally referenced at 20 ) consisting of a substantially beaker-shaped body 21 closed above by a cover 22 , for example circular and secured with screws Or other blocking devices are detachably fixed on the beaker main body 21.

Abstract

A dispensing device (50) of an additive for a filter groups (10) of internal combustion engines, comprising a variable-volume tank (51) able to contain an additive from which a conduit (52) for dispensing the additive branches, characterised in that it comprises at least a porous membrane (54) having a fixed depth internally of the conduit and able to intercept the flow of additive being dispensed from the tank (51).

Description

technical field [0001] The present application relates to a supply device for additives for a filter set of an internal combustion engine, a filter element comprising said device and the associated filter set. [0002] More specifically, the invention relates to means of dispensing additives suitable for improving the quality of the fuel supplied to internal combustion engines in terms of lubricating qualities and / or anti-corrosion properties, and which can be integrated in filter groups for said dyes. Background technique [0003] Dispensing devices for fuel additives associated with fuel filter banks are known. [0004] The spreading device comprises a variable volume container for containing the additive to be injected into the fuel, for example downstream of the filtration stage. [0005] The means for dispensing additives is branched off from said container, and between said container and the pipe, for example, a first non-return valve is provided to prevent filling of...
