Translation of "Coolant filter" in German

However, an unexpected leaking of pressurized coolant from the filter interior is no longer possible in this position of the cover, because the stop valve and the check valve actuated in a pressure-dependent manner have closed off the filter interior with respect to the remaining coolant circuit, so that the filter insert can now be removed safely.

As part of your cooling system maintenance program, it's a good idea to occasionally inspect a used coolant filter in an effort to detect potential problems.

This ingenious coolant filter is a reliable, sensible, good value for money alternative to conventional systems such as centrifuges or band filter units.

In a further preferred embodiment of the invention, at least one fluid circuit component is a coolant pump, a coolant filter or a coolant sensor for the battery cell pack, which thus renders these assemblies easily accessible for maintenance replacement.

SUMMARY OF THE INVENTION The invention aims to improve a generic coolant conditioning unit to make it possible to change the filter insert safely and, in particular, to open the coolant filter safely.

A check valve can be provided in this return line, so that during normal operation—driven by the coolant pump—a higher pressure prevails on the clean side of the coolant filter than in the remaining coolant circuit, whereby the “remaining coolant circuit” is understood within the scope of the present invention to be the sections of the coolant circuit that connect directly to the mentioned valves provided according to the invention.

But since the filter is designed merely as a partial-flow filter anyway and merely a part of the overall recirculated coolant filter, this bypass of the filter insert 6 does not represent any relevant impairment of the filter function.

Directly behind its end the tube is bent through 180° and extends with its upwardly open part along the outer surface of the rotating coolant filter.

In another embodiment the pressure tube lies with its open part at a slight spacing in front of the outer end face of the rotating coolant filter.

In both cases the thus channeled air flow of the tube blows particles out of the holes of the rotating coolant filter, or at least blows out those particles that are fairly light and are not lodged in place.

In the region inside the coolant filter the tube, which carries the filter, is formed on its lower side with a hole on which an downwardly open outlet is connected that extends close to the surface and reaches over a portion of the end of the rotating filter.

Here a housing is set from outside on the end and side of the coolant filter that is at least partially open on its side directly juxtaposed with the filter.

However, it is good practice to utilize a coolant filter with no SCA in an effort to remove any contaminants that may be a part of the cooling system.

On the one hand, they make it possible to extend the useful life of the coolant by filtering it.

Coolant filters are available without SCAs if the use of liquid BTE or BTA PLUS additives is preferred.

According to an advantageous development of the invention it is therefore provided that as a medium the filtered coolant/lubricant of a machine tool is used.

In this machine, during the measuring run the sliding bearings are lubricated with filtered coolant used for cooling the balancing tool during the balancing operation.

Liquid coolant filters function in engine cooling system as by-pass filters where only part of the liquid flows through.

It is used in healthcare as pillows and sheets for patients (in permeable and impermeable form), wipes, bibs, etc., in agriculture and the food industry for filtering milk, oil, wine and other foods, for burial services as an ecological lining for coffins and graves, in engineering for filtering coolant and cutting emulsions, and in the construction industry as a roof underlay component.
