DESCRIPTION:
BRIEF SUMMARY
This invention relates generally to filter devices and more particularly, although not exclusively, to devices for filtering the coolant in internal combustion engines
Many internal combustion engines include a cooling system in which a coolant such as water is pumped around a circuit which passes adjacent hot sections of the engine and returns to a radiator in which the heat from the water circulating in the cooling system is dissipated. The radiator generally comprises a header tank disposed above a core which comprises a number of tubes in which the heat is dissipated as the water passes through those tubes. Owing to the hot water circulating through the coolant circuit a formation of corrosion and minute deposits of iron rust or corroded aluminium tend to occur. These formations can cause serious problems as they may block up the tubes in the radiator core and therefore reduce the efficiency of the radiator or in some cases prevent the flow of fluid altogether which can lead to serious overheating of the motor.
It is an object of the present invention to provide a filtering device which is suitable for use in the cooling system of an internal combustion engine which assists in inhibiting or reducing the possibility of radiator blockage.
According to the present invention there is provided a filtering device for use in a cooling system for motors or engines such as for example vehicle or boat engines or alternatively stationary engines having a cooling circuit around which the coolant passes, the device including a bag-like member which is comprised at least in part by mesh material, the bag-like member, in use, being disposed within the coolant circuit, so that the coolant passes through said mesh material and so that said bag-like member collects deposits carried by the coolant therein.
Preferably the bag-like member comprises a flexible tube-like element having one end closed and the other end defining a mouth. Preferably the bag-like member is substantially totally formed of mesh material.
The device may further include a magnet which is disposed within the bag-like member and arranged so that it tends to collect metal fines on it as the coolant liquid flows through.
The device is adapted for use in a cooling system for a motor which includes a radiator having an inlet pipe and a header tank. The device may further include means for attachment of the mouth of the bag-like member to the inlet pipe the bag-like member being dimensioned so that it can pass through the inlet pipe into the header tank.
In one preferred form the bag-like member is formed of a stretchable material so that the mesh size of the mesh material can increase in size under pressure. This has the advantage that as the bag fills up with deposits there may be a resistance to flow, however, as pressure builds up the bag can stretch thereby assisting in the passage of coolant therethrough.
A preferred embodiment of the invention will herein be described with reference to the accompanying drawings in which:
FIG. 1 is a schematic side elevation of the cooling circuit of an internal combustion engine; and
FIG. 2 is a more detailed view of FIG. 1 showing the filtering device of the invention.
Referring to the drawings, the filtering device generally indicated at 15 comprises a bag-like member 16 which in the form shown is comprised of a mesh material. The bag-like member, in use, being disposed within the coolant circuit (1) of an internal combustion engine the circuit including a radiator 2 having an inlet pipe 3 connected to the engine 5 and an outlet pipe 6 also connected to the engine 5. The radiator 2 further includes a header tank 11 and a core 12 having a plurality of tubes therein. The coolant is pumped around the current by means of a pump 8 connected to fan 10.
The bag-like member 16 is secured to the inlet pipe 3 of the radiator 2 and is disposed within the upper header tank 11. As shown the bag-like member may be constructed from a flexible tube-like element having one end closed and the other end defining a mouth 19. Any suit
