Detailed Description
Referring to fig. 1 to 4 in combination, according to an embodiment of the present invention, there is provided a fixed scroll including a fixed scroll body 1, a discharge port 11 is configured on the fixed scroll body 1, a discharge spool 2 is disposed in the discharge port 11, the fixed scroll body 1 has a toothed side and a non-toothed side, the discharge spool 2 is capable of generating a linear motion away from the toothed side to conduct the discharge port 11 when the compressor discharges air, and the discharge spool 2 is capable of generating a linear motion close to the toothed side to block the discharge port 11 when the compressor does not discharge air. In the technical scheme, the exhaust valve core 2 which can move along the axial straight line of the exhaust port is adopted to replace a valve plate structure at the opening of the exhaust port in the prior art, so that the risk that the exhaust valve plate is recessed into the exhaust port 11 due to the fact that the pressure on the back surface (outer side) of the fixed scroll is far greater than the pressure of a central compression cavity (inner side) of the fixed scroll can be effectively avoided when the compressor is stopped, and meanwhile, the over-compression phenomenon caused by the thickness of the valve plate does not exist.
As a specific structure of the exhaust valve core 2, preferably, the exhaust valve core 2 includes a blocking plate 21 and an annular plate 22, the annular plate 22 is connected to the blocking plate 21 by an annular wall 23, a plurality of through holes 24 are configured on the annular wall 23, the annular plate 22 is located at one side of the blocking plate 21 close to the toothed side of the fixed scroll body 1, that is, the exhaust gas in the fixed scroll is applied to the blocking plate 21 via a central area (through flow) of the annular plate 22, so that the exhaust valve core 2 can be forced to move linearly toward the non-toothed side, when the through holes 24 communicate the exhaust port 11 with the non-toothed side of the fixed scroll, so as to exhaust the exhaust gas, and when the compressor is not exhausting the exhaust gas, the pressure at the non-toothed side of the fixed scroll will be higher than the pressure at the toothed side, under the self weight of the exhaust valve core 2 and the pressure difference, the exhaust valve core 2 will block the exhaust port 11 by moving linearly toward the toothed side.
It can be understood that the linear motion of the exhaust valve core 2 in the exhaust port 11 has a corresponding limit structure to limit the displacement range of the linear motion, as a preferred embodiment, the opening of the exhaust port 11 on the toothless side of the fixed scroll body 1 is provided with a limit retainer 3, the limit retainer 3 has a through hole 31, the diameter of the through hole 31 is not smaller than the outer diameter of the blocking plate 21, and the diameter of the through hole 31 is smaller than the outer diameter of the ring plate 22, and the limit retainer 3 is detachably connected with the fixed scroll body 1 by screws. At this time, the linear motion of the exhaust valve element 2 toward the toothless side is limited by whether the limit check ring 3 contacts the ring plate 22 or not.
In order to improve the sealing effect of the exhaust valve core 2 on the exhaust port 11, a first annular groove 211 is formed on the outer peripheral wall of the blocking plate 21 and is used for embedding a sealing ring 4; and/or, the hole wall of the through hole 31 is configured with a second annular groove 311 for embedding a sealing ring 4, the sealing ring 4 may specifically adopt an oil-resistant rubber ring, and it can be understood that, when having the corresponding first annular groove 211 and the second annular groove 311 at the same time, the groove depths respectively provided by the two annular grooves cannot be too large, so as to ensure that the sealing ring 4 can be smoothly followed by the reciprocating linear motion of the closure plate 21 after being deformed or form a whole with the through hole 31.
