Embodiment

Thermostat is the assembly that is positioned between motor and the cooling system (radiator).Its effect is the flow velocity of control radiator coolant and engine coolant, keeps operating temperature to be in the ideal range, prevents that the overheated or cold excessively of galling more from appearring causing in engine operating state.The integrated type thermostat comprises: workpiece 7, support the endless belt 8 and the pressure spring of whole device, and all these parts are assemblied in lid or cover on 9, by polymer/metallic or nonmetallic material manufacturing, and obtain by structure, injection or machining.

According to the scheme that the utility model proposes, change integrated type thermostat lid or cover 9 structural configuration by other assembly is set so that gather other function, these assemblies as:

● temperature transducer 1;

● be used to connect the pipe 2 of hot system (abtacle);

● the routine pipe 3 of the tight radiator hose of bolt;

● alternative vent systems 4;

● pipe joint 5;

● sealing system 6.

Device

This thermostat has outlet device.In this case, thermostat receives the liquid from motor, by its operation element, regulate and wait to flow to (cooling but) radiator liquid flow velocity and continue flow velocity in engine interior circulation (and not cooling off).

Functional character:

Open to start: open that to start be that thermostat valve will allow the go into circulation feature of radiator of cooling liquid when temperature actuated.In the design, can start for several engine application change to open.

Stroke: stroke is to improve according to temperature to produce the feature of opening; In the case, thermostat valve will be worked and be made cooling liquid be passed to radiator.In the design, can change the stroke of several application.

Leak: leakage is that system's supercharging and thermostat valve produce the feature that the cooling liquid that at utmost allows to leak into radiator is leaked when closing.In the design, can change the stroke of several application.

Consolidation function:

Temperature transducer 1:

This is the assembly that shows temperature variation in the valve zone.The effect of this temperature transducer 1 is the center (handle and manage so that carry out motor according to the temperature of cooling liquid, and/or show coolant temperature in Vehicular instrument panel) that data input signal is sent to electrojet.

Can this temperature transducer 1 be set by changing length and the tight angle of bolt; Can be by screw thread, clip or this temperature transducer 1 of the interference fit that covers, and can lead to glue or by the sealing of ring sealing system.

Heating system pipeline 2:

It allows hot cooling liquid to be passed to the heating system of vehicle interior.Can obtain many forms:

● pipe is injected at lid.Can adopt or not adopt the secondary process process to obtain this pipe, and can this pipe be set by changing length, inside/outside diameter and the tight angle of bolt.

● pipeline is used plastics, metal or nonmetal manufacturing separately, and is covering by screw fit, and perhaps the two is by interfering or the gap assembling, and this pipe uses glue as the bolt tight seal.

The pipeline 3 of fastening radiator hose:

It allows cooling liquid to be passed to radiator.The pipe of this pipe and heating system 2 can also can obtain by tradition and/or special manufacture process, and by variation length, inside/outside diameter and the tight angle of bolt it is provided with aluminium, plastics, metal and nonmetal making.

Vent systems 4:

Can alternative vent systems or " venting " be set by ball, fine motion pin or the indenture system that is positioned on workpiece lid 7 or even the thermostat cover 9; The effect of valve is to allow air can also realize system exhaust in the mode of not using outlet valve or fine motion pin by the peak in the thermostat field flow orientation motor (normally expansion tank) when being full of hot liquid.In these cases, the flexible pipe that passes pipe joint in the thermostat is arranged, be used to remove the air in the element area.

Pipe joint 5:

Pipe joint 5 also has the effect of removing air in the refrigeration system; It can be with plastics, brass, metal and nonmetal making, and by changing length, inner and outer diameter and the tight angle of bolt it is provided with.Can it be assemblied on the thermostat cover 9 by screw thread, interference or gap approaches, use glue as the bolt tight seal.

By quick joint or suitable shape, and/or adopt neck/flexible pipe to interfere and realize that pipe joint 5 contacts with the tank for coolant flexible pipe, guarantee that by using clip and/or clamping plate the flexible pipe bolt is tight.

Sealing system:

Sealing system is responsible for guaranteeing that cooling liquid is not from thermostat particularly in the assembly area between valve flange and head and/or spill in the motor.This system can comprise and allows several shapes that selection (square, rectangle, circle or special shape) paper or metal joint or seal ring 6 are set.Seal ring 6 can embed in cover 9 the cover body, forces its self adaption, and fills up irregular on two parts, and any gapped, strengthens the effect that barrier liquid leaks.Some point on sealing ring 6 girths can increase several stopping with various forms, and purpose is that the seal ring bolt is tightly also formed the assembling indication in the caulking groove within it.

All these assemblies are added on the flange plate 10, and flange plate 10 comprises hole 11, and is by the tight bolt of motor bolt that passes hole 11 that thermostat is disposed thereon.

Following assembling selection is considered in the design of integrated type thermostat:

1. be equipped with sensor and pipe joint (Fig. 9);
