Description
Technical field
The present invention relates to a kind of temperature regulator that is particularly useful for internal combustion engine, it especially is used in pure (cleaning) air intake duct of internal combustion engine or in the air inlet filter shell.
Background technology
Such temperature regulator is for example known from the general automobiles internal combustion engine, the shortcoming of this known temperature regulator is its fixing relatively effort on internal combustion engine, seal and make for this temperature regulator punching press fixing with the clamping tongue of needing a special processing are so that closely be connected temperature regulator with shell such as the air inlet filter box.
Summary of the invention
Therefore, the device that the objective of the invention is this paper is started described kind improves, thus invent a kind of can safety, reliable, easy and the temperature regulator that uses on internal combustion engine in the expense lowland.
According to the present invention, above-mentioned task solves by such temperature regulator, this temperature regulator comprises a shell, the aeration regulation valve of a temperature dependent, at least two control conduits that have the throttling xsect of a calibration respectively, wherein, can be inserted and secured on hermetically in the pure air duct or in the filter box by bimetal regulator.So not only installation but also the whole device of transportation in logistics easily easily is because only need the separate part of an integral body of disposal now.Can save producing cost in addition, because cancelled rubber seal that is adopted so far and the iron stamping parts that is used for fixing.
In a favourable concrete structure of the present invention, the regulation shell has positioning block tongue, temperature regulator can be inserted in the shell of air inlet filter box by means of this positioning block tongue.Positioning block tongue works according to the mode of barb, prevents that temperature regulator from loosing from its installation site.
In another favourable concrete structure of the present invention, regulation control conduit has positioning block tongue.It is a kind of modification of positioning block tongue fixed form that positioning block tongue is placed on the control conduit.In the time of on being fixed in shell, big than in the control conduit road organization plan of the installing port in the air inlet filter box then, this needing to cause the seal with bigger.Positioning block tongue being placed under the supravasal situation of control, then only need the zone of the very little basically loading port of sealing, further save employed encapsulant thus.
Can also stipulate according to the present invention that in addition breather valve or variable valve have a bimetallic thermostat, bimetallic thermostat is than the in use more reliable and easier adjusting of comparable wax formula thermostat.
A favourable concrete structure regulation shell of the present invention is made of plastic material.Adopt plastic material to be convenient to the recovery when terminate serviceable life from now on, especially when plastic material is indicated its feature.In addition, single parts of shell and seal composition also have only by adopting plastic material just can become possibility.
In another favourable concrete structure regulation, sealing flange of injection moulding on shell reduces the number of the single parts in this functional module by the injection moulding sealing flange, thereby saves cost and help assembling.
Can stipulate according to the present invention, in the device of an intake air temperature of regulating the compressed mixed IC engine, have an operation valve in the thick pneumatic fitting that is installed in breather filter, this valve and a pneumatic control gear acting in conjunction, and make a retracing spring motion of passing a pulpit in pneumatic control mechanism at an end position, a hot air chamber is closed, simultaneously a cold air channel is opened, wherein the control conduit of the throttling xsect of the pulpit of pneumatic control mechanism through having calibration is connected with the channel part in the downstream that is positioned at the air throttle that can handle arbitrarily of air intake duct, in the control conduit, a breather valve that moves according to variation of temperature is set, it is made of a bimetallic thermostat that acts on the valve body, this bimetallic thermostat is installed in the space that is encased by a housing, this space is in the connected state of unlatching all the time through the pure air plenum of at least one opening and air inlet filter, and control conduit road is passed in the space that comprises thermostat, this space has another through the linkage path of thermostat by the pure air plenum that leads to air inlet filter of valve body control, has used one according to temperature regulator of the present invention.In a this functional module, use this temperature regulator and bring benefit for constantly forward the development of the module that will invent.
The feature of these and other of favourable concrete structure of the present invention can obtain from instructions and accompanying drawing; wherein each independent feature itself can be individually or carry out realizing in combination of various ways mutually in enforcement structure of the present invention and in other field; and can show favourable and the embodiment that itself has protective capability, the present invention has required protection at this to these embodiments.
