[Prior Art] A piston body applied to an air compressor has a main structure in which a valve passage of a piston body is provided with a vertical communication passage, and one end of an elastic metal valve plate is fixed to the valve head at other ends. It is completely enclosed above the channel. When the piston body reciprocates in the cylinder chamber, the valve will open and close at the frequency of the 鬲 frequency, and the maximum stress at the fixed end of the valve plate is exceeded. The stress generated in the top plane of the flapping valve head during operation is easy to deform and bend the fixed end, so that the valve plate can not form an airtight effect on the passage, and the compression function of the air compressor is lost. The present inventors have sensed that the valve plate is designed such that an outer ring piece is coupled to an inner piece ′ so that the valve piece is divided into a two-stage cleavage state and subjected to a small stress ′, which is less likely to be damaged than the previous structural design. 5 200831785 [Description of the Invention] The present invention relates to a piston body structure of an air compressor, in particular to a valve plate structure provided on a valve head of a piston body, and a valve piece is arranged on the valve head of the piston body, and the valve piece is arranged There is a ring inner space, the valve piece is divided into two parts: the outer ring piece and the inner piece piece, so that the vibration stress of the valve piece can be evenly dispersed when the valve head is slammed, and the stress concentration is less likely to occur and in the neck section or It is a phenomenon that the fixing section is creased and cannot be airtight. The valve plate is provided with two positioning holes, which can be fixed to the positioning post on the valve head.

The airtight effect, or the valve (1) can reduce the noise generated by the slap when the opening and closing action is performed and the valve head (23) is tapped. A piston rod (21) is arranged at a lower end of the valve head (23), a shaft hole (22) is arranged at a lower end of the piston rod (21), and an oil seal ring is arranged around the valve head (23) (the sentence head (23) is The peripheral wall of the cylinder chamber (69) is airtightly combined to prevent gas bubbles. A valve piece (1), the wide piece (1) is provided with an annular inner space (14), and the circular valve piece (1) Divided into two parts, the outer ring piece (11) and the inner piece (13), the outer ring piece (11) and the inner piece (13) are joined to form a neck section (12) opposite to the neck section ( 12) The outer ring piece (11) is further formed with a fixing section (17) having two positioning holes (15) (16). The valve piece (1) is fixed by two positioning holes (15) (16). The positioning post (25) (26) on the top surface (24) of the valve head, and the inner disc (13) of the valve piece (1) can close the passage (28) of the valve head (23), and the whole assembly is completed as the second The state shown in the figure. * Please refer to the sixth to eighth figures. A gas collecting seat (61) is set on the cylinder block (6). The gas collecting seat (61) is provided with a gas collecting chamber (60) for collecting gas. The top cover (66) of the seat (61) is provided with a spring (67) and a valve seat (68), and the valve seat (68) can be elasticized by the magazine (67). a passage (690) of the gas collection chamber (60) and the cylinder chamber (69); a plurality of manifolds (62) (63) (64) (65) are disposed around the gas collection seat (61), and the manifold (64) The hose (641) and the nozzle (9) at the end thereof can be connected, the manifold (65) can be connected to the hose (651) and the barometer (8) at the end thereof, and the manifold (62) can be equipped with, for example, Deflating valve body (81). When the 200831785 piston body (2) is pushed up, the air can push open the valve seat (68) into the plenum (6〇), and then the manifolds are rotated out to the nozzle (9), air pressure (8), no gas valve body (81).
