Problems solved by technology

[0004] However, the conventional reed valve restrictor is composed of a metal plate fixed to the valve body with screws, resulting in a large number of parts and many assembly steps.
In addition, in the conventional technology, there is a problem that the movement of the reed valve is restricted due to fluid resistance such as air sandwiched between the reed valve and the restrictor.

Embodiment Construction

[0032] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following embodiments, although various limitations are made to the constituent elements, types, combinations, shapes, relative configurations, etc., these are merely examples, and the present invention It is not limited to this.

[0033] Fig. 1 is a schematic diagram of a secondary air system using a reed valve as a first embodiment of the present invention. In this embodiment, the secondary air system is used as an example for description, but the system using the reed valve is not limited to the secondary air system, for example, an air intake system may also be used.

[0034] The suction pipe 12 is arranged at the suction port 11 of the cylinder head 10 as the power, and guides the air into the cylinder through the air filter 13 . An exhaust pipe 15 is attached to the exhaust port 14, and the exhaust pipe 15 is connected to...

Abstract

The present invention relates to a reed valve (19) which uses the reed shaped valve body (23) to control the air inflowing. A fixed end (23A) of the reed shaped valve body (23) which is used to block the valve port (25) is installed on the valve main body (24) arranged with the valve port (25). The first bending part is composed by bending the free end (23B) of the valve body (23) to the direction of the valve main body (24) and the second bending part is formed by bending the free end of the valve to the inverse direction to the fixed end (23A). A tieing stop hole (27) is arranged at the valve installing surface (24S) of the installing valve body (23) of the valve main body (24). The bended free end (23B) of the valve body (23) is inserted into the tieing stop hole (27). The free end (23B) is tieing stopped at the position where the second bending part (232) contacts the step part (27A) of the tieing stop hole (27) if the valve body (23) is warped by the pressure. In this way the valve can prevent that the valve body (23) is warped by the excess to the elastic limit. The invention provides the waste stop as the reed valve restricting piece and low price reed valve of other objects.

Description

technical field [0001] The present invention relates to a reed valve for controlling the inflow of air using a reed-shaped valve body. Background technique [0002] In the reed valve, there is a reed valve limiter. When inhaling or exhausting, in order to prevent the reed valve body from overtraveling and causing excessive stress and cannot return to the original shape, the above-mentioned reed valve limiter is used to limit the valve. body warping (Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-232712 [0004] However, the conventional reed valve restrictor is constructed by fixing a metal plate to the valve body with screws, and there are many parts and many assembly steps. In addition, in the prior art, there is a problem that the operation of the reed valve is restricted due to fluid resistance such as air sandwiched between the reed valve and the restrictor. Contents of the invention [0005] The present invention is made to solv...
