"Device for regulating the liquid circulation cooling for internal combustion engines in particular of: motor vehicles "

The subject of the invention relates to a device for regulation the temperature of circulation cooling systems for internal combustion engines, in particular for motor vehicles.

It is about a two-circuit system in which a mixing valve is built-in, each steplessly from the small circuit can switch to the big cycle.

When the motor starts up, the cooling water flows from the pump to the motor and from there through the mixing valve back to the pump. This State remains until the desired levels in the internal cycle are reached. The mixing valve that is attached to the lower part of the The cooler is connected, then so much chilled water is in the inner circuit that its temperature is neither exceeded is still below

When it is very hot, the control valve moves up so that the upper valve can close the inner or small circuit, and the full flow of water then goes through the lower valve, * "via the water pump, through the engine and directly to the radiator.

^r The mixing valve is also able to maintain the desired level during the strongest frost, because there is very small amounts of chilled water in the inner or small circuit.

It is hereby achieved that the mixing valve, regardless of the outside temperature, always the same mixed water for There is an engine whose temperature is constantly maintained at the same level, and cooling water ingress, as it has been with the previous ones The fee schedule of the German Chamber of Patent Attorneys is binding for the contractual relationship.

Systems that are lall can be effectively avoided.

In the drawing, the subject of the invention is for example shown, namely show:

Fig »1: a longitudinal section of the cooling water Eeguliermiso valve,

Order this to make the cooling water regulating valve cheaper preferably from standardized parts already commercially available for other purposes and otherwise from turned parts, while the housing itself is mainly made of metal, brass, aluminum, as well as plastic.

Worn motor housing 1 leads the cooling water pressure line 2 to the radiator 3 and from there through the suction line 4 to the chamber of the housing connector 6 to the lower part of the regulating valve and a second pressure line leads as a branch line 7 directly to the connector 8 of the upper chamber 9 of the EegpLierventiles. Between the chambers 5 and 9, the mixing chamber 10 is switched on, in which, under the arrangement of a thermocouple, the hot water coming from the line 7 is mixed with the cooled water coming from the cooler line 4 and from here at the desired temperature via the nozzle 11 of the Suction line 15 flows in.

The flow control of the hot water from the chamber 9 and the cooled water from the chamber 5 ^{to: c} mixing chamber 10 is carried out by the two alternately controlled poppet valves 17, 18 influenced by the thermocouple 12.

The valve guide is taken over by the columns 16 independently of the expansion element 12. By means of the adjustable and lockable Adjusting screw 15 is the beginning of the stroke of the working element ^ s; set. The piston of the working element 12 has no fixed connection with the lower bracket 15 &, and its adjusting screw 15, so that the valve and working element can work freely, no jamming occurs and the valves are well sealed

is guaranteed. As a result of the separation is further only there is little heat transfer. Juzch, the work element is completely encapsulated from the cold water side.

The mixing valve and the valve itself can be dismantled kept interchangeable.

In the case of production in metal, three columns 16 distributed around the circumference are expediently provided, while in production Four pillars are advantageously used in plastic

Claims (6)

Ρ.Α.2Ί2 361 * 4/29/67 _ 4 _ Protection claims 1.)
