Abstract
The utility model relates to a nesting-type intake-exhaustion machine, which is characterized in that when a main valve top plate is pushed, a main valve which is connected with the main valve top plate is also pushed, so that a sealing surface between an air cylinder head and the main valve can be opened, the air cylinder head and the main valve can be communicated with an air passage, and air circulates; and when the main valve top plate is further pressed downwards, a central valve top pin which is connected to the main valve top plate can push a central valve, a central air passage is opened, the air is communicated with the central air valve through the central air passage, so that the flow rate of the air is further increased, and the intake-exhaustion efficiency can be improved.
Description
Technical field
The present invention is a kind of set type intake and exhaust mechanism in the mechanical device technical field, through total valve air flue and central valve air flue, has further strengthened the flow of air, improves its intake and exhaust efficient.
Background technique
Common exhaust gear does not have the air flue connection at present, can not improve intake and exhaust efficient.
Summary of the invention
The purpose of this invention is to provide a kind of set type intake and exhaust machine mechanism; Total valve through when promoting total valve top board, being attached thereto also is pushed; Cylinder head and sealing surface between total valve are opened are communicated with, ventilate, improve its intake and exhaust efficient with air flue.
Its objective is such realization; Air flue and sealing surface are arranged on cylinder head among Fig. 1; Total valve, total valve spring are housed in cylinder head, and total valve is connected with total valve top board, in total valve, central valve, central valve spring is housed again; And have central airway, be connected with central valve ejector pin on total valve.
Total valve through when promoting total valve top board, being attached thereto also is pushed, and cylinder head and the total sealing surface between valve is opened is communicated with air flue, ventilates; When total valve top board further when pressing down; The central valve ejector pin that is connected above total valve top board will back down central valve, and opens central airway, and air is through central airway and the circulation of central valve; Further strengthen the flow of air, improved its intake and exhaust efficient.
Description of drawings
Concrete structure of the present invention is provided by following examples and accompanying drawing:
Fig. 1, be a kind of set type intake and exhaust of the present invention mechanism structure schematic representation.
Fig. 2, be intake and exhaust of the present invention mechanism plan view.
Among Fig. 1, Fig. 2,1, sealing surface, 2, air flue, 3, cylinder head, 4, central airway, 5, central valve spring, 6, total valve spring, 7, total valve, 8, central valve, 9, total valve top board, 10, central valve ejector pin.
Embodiment
Specify the concrete working condition that the present invention proposes below in conjunction with Fig. 1; Air flue (2) and sealing surface (1) are arranged on cylinder head (3) among Fig. 1; Total valve (7), total valve spring (6) are housed in cylinder head (3), and total valve (7) is connected with total valve top board (9), in total valve (7), central valve (8), central valve spring (5) is housed again; And have central airway (4), be connected with central valve ejector pin (10) on total valve (7).
Total valve (7) through when promoting total valve top board (9), being attached thereto also is pushed; Cylinder head (3) and sealing surface (1) between total valve (7) are opened to be communicated with air flue (2); Ventilate, when total valve top board (9) further when pressing down, the central valve ejector pin (10) that is connected above total valve top board (9) will back down central valve (8); And open central airway (4); Air has further strengthened the flow of air through central airway (4) and central valve (8) circulation, improves its intake and exhaust efficient.
Claims (1)
