Abstract

1511002 Disposable air filter TECAFILTRES 24 April 1975 [24 April 1974] 17123/75 Heading BIT A disposable filter for an I.C. engine air intake comprises a housing whose two halves are permanently joined together to enclose an annular filter element (Fig. 3 not shown), the top of the casing including a diaphragm 20 which moves downwards when the pressure in zone 27 falls, as a result of the filter element clogging, so that metal strip 21 completes a circuit between contacts 22, 23 to actuate a sound or light signal that the filter requires changing. Diaphragm 20 can be a separate member or part of the housing wall (Fig. 5 not shown). The housing halves are of metal or polypropylene and joined together by rivets, glueing, crimping or welding. One or both halves has inwardly projecting posts (8) to engage the other half to resist crushing of the housing. The filter element is of foam or pleated paper, and its ends are set in layers of adhesive in annular troughs of the housing halves. Strip 21 may be of the fast-acting type which suddenly changes shape under stress.
