Description

Connection structure between valve element and intake element of engine

The present invention relates to a connection structure between a valve element for an engine and an intake element, and more particularly to a connection structure for improving the degree of freedom of connection between a valve element and an intake element of an engine.

According to the connection between many valve elements of the engine of a general locomotive and the connecting parts of the intake element, generally, the pipe type is commonly used as a connecting member, in particular, a connection between a solenoid valve component and other mechanical components. For example, between the throttle body 1 for providing fresh air outside the engine and the idle bypass valve 2, that is, connected by the vent line 3, as shown in Fig. 1, the connection of the conventional pipeline 3 is mainly caused by the section. The flow valve body 1 is provided with a connection joint 11, and the other idle bypass valve 2 is also provided with a connection joint 21, which is respectively connected to the connection joint 11 of the throttle body 1 by the pipe 3, and the connection joint 21 of the idle bypass valve 2 And the bundle 3 is bundled at the junction of the pipeline 3 and the joints 11, 21, thereby forming a stable connection between the pipeline 3 and the joints 11, 21, thereby making the throttle body 1 and the idle bypass valve 2 forms a connection. The valve element of the above-mentioned engine and the intake element (the throttle body 1 and the idle bypass valve 2) are connected by the pipe 3, although the valve element and the intake element of the engine have been reached (throttle The purpose of connecting between the valve body 1 and the idle bypass valve 2). However, it is connected by the pipe 3, and the arrangement of the pipe 3 undoubtedly causes the space between the parts to be very limited, and when the pipe 3 is easily twisted, the inside of the pipe 3 is caused. The cross-sectional area changes, which in turn affects the accuracy of the amount of fluid in the line 3; the other line 3 has a certain length, thus increasing the doubt that the line 3 is broken and leaking.

In view of the connection between the valve element and the intake element of the conventional engine, the line 3 is used as a connection to have the above-mentioned deficiency, so that the degree of freedom between the valve element and the intake element of the engine is improved. It is an urgent issue for locomotive manufacturers.

The main technical means of the present invention provides a connection structure between a valve element for an engine and an intake element, and includes a male joint tube having a valve element and a female joint tube of the intake element, mainly comprising: a soft adapter, The flexible adapter has a first plug portion, a second plug portion and a trim portion; the first plug portion has a through hole and a flange, and the through hole communicates with the second plug portion; the second plug The connecting portion has an opening and a ring groove communicating with the opening; the reinforcing portion is configured to be bundled by the bundle ring; the flexible adapter is combined with the male tube and the female connector tube to thereby lift the engine The degree of freedom of the connection between the valve element and the intake element.

In order to make it easier for the examiner to understand the structure of the present invention and the efficiencies that can be achieved, the following description will be made with reference to the following figures: First, referring to Figures 2 and 4, the valve element and the intake element of the engine of the present invention are shown. The connection structure includes a flexible adapter 4, a male connector 51 of the valve member 5, and a female connector 61 of the intake member 6; the flexible adapter 4 is made of a soft plastic material, including the first The insertion portion 41, the second insertion portion 42 and the reinforcing portion 43; the first insertion portion 41 has a through hole 411 which penetrates from the outer side of the flexible adapter 4 to the second insertion portion 42 and The second insertion portion 42 is convexly provided with a flange 412, and the other side of the flange 412 is provided with an opening-shaped socket 413; the second insertion portion 42 is in communication with the first insertion portion 41. The inner diameter of the second insertion portion 42 is larger than the inner diameter of the through hole 411 of the first insertion portion 41. The second insertion portion 42 has an opening 421, and the second insertion portion 42 is connected by the first insertion. The flange 412 of the portion 41 and the inner side wall 43a of the reinforcing portion 43 form a receiving ring groove 422; the reinforcing portion 43 can be bundled by the bundle ring 7, and the reinforcing portion 43 is located at the opening of the second insertion portion 42. The outer edge 421 is provided with a flange seat 431.

The coupling structure of the engine valve member 5 and the intake member 6 of the present invention is implemented as an air cleaner or a throttle body, and the valve member 5 is a secondary air control valve or idle speed. By-pass valve; the following description is exemplified by the connection of the throttle body (intake element) 6 and the idle bypass valve (valve element) 5, but the scope of use of the joint structure of the present invention is not limited thereto. First statement. Referring to FIG. 2, FIG. 3, FIG. 4 and FIG. 5, the female joint pipe 61 is disposed on the throttle body 6, and the female joint pipe 61 communicates with the inside of the throttle body 6; the male joint pipe 51 is connected to On the idle bypass valve 5, the male joint 51 is in communication with the inside of the idle bypass valve 5, the male joint 51 is provided with a hook portion 511; and the female joint tube 61 is inserted into the second plug of the flexible adapter 4 In the connecting portion 42 , the end 611 of the female connector tube 61 is inserted into the bottom of the annular groove 422 of the second insertion portion 42 , and the male connector tube 51 is inserted into the socket 413 and the through hole 411 of the first insertion portion 41 . And the hook portion 511 of the male connector 51 abuts against the flange 412 of the first plug portion 41; and then the bundle portion 7 of the flexible adapter 4 is bundled with the bundle ring 7, the bundle portion The bearing flange 431 of the sleeve 43 can be seated by the bundle ring 7 to complete the connection operation of the connection structure. The female joint tube 61 of the present invention can be disposed on the valve element 5, and the male joint tube 51 can be disposed on the valve member 5 On the intake element 6.

The effect of the present invention is that the flexible adapter 4 can be used to simplify the connection between the valve element of the engine and the intake element (such as the throttle body 6 and the idle bypass valve 5). The space is no longer limited, and thus the degree of freedom between the valve element of the engine and the intake element (such as the throttle body 6 and the idle bypass valve 5) is greatly increased; the valve element and the intake element of the engine (For example, the connection between the throttle body 6 and the idle bypass valve 5) is no longer connected by a narrow pipe, so that the accuracy of the fluid amount of the idle bypass valve 5 can be greatly improved; Reducing the bundle point between the valve element of the engine and the intake element (such as the throttle body 6 and the idle bypass valve 5), thereby further reducing the occurrence of leakage doubts; more importantly, due to the softness The adapter 4 is made of a soft plastic material, so that the flexible adapter 4 can be used as a cushioning member to absorb vibration, thereby further protecting the electronic components in the idle bypass valve 5 from vibration.

In summary, the present invention has been improved by the conventional use of the valve element of the engine and the air intake element, and has become a novelty and a progressive element. For the detailed examination of your review committee, Huisei is approved for the grant of patents.
