The invention relates to a device in an appliance for the treatment of oil for the lubrication of an engine, preferably an oil filter and/or an oil cooler for an internal combustion engine. Thereis a valve (11) designed, when the oil pressure exceeds a predetermined value, as a result of dirt deposits in the appliance, for example, to connect the oil inlet of the appliance directly with the oil outlet of the appliance. According to the invention the device partly comprises a pipe (6), the wall of which constitutes a dividing wall between the oil inlet and the oil outlet and in which wall there is at least one opening (11a, 11b). In addition there is a ring (11c) of an elastically resilient material, congruent with the cross-section of the pipe wall and at least partially bearing against this on the oil outlet side of the pipe (6), the shape of the ring corresponding to the cross-sectional shape of the pipe. A valve cone (11d, 11e), functionally connected to the ring or integrally formed therewith, is designed to seal the opening (11a, 11b) when the oil pressure is below the said pressure value, the wall of the opening thereby forming a valve seat, and to reveal the opening when the oil pressure exceeds the said value. |
