A discharge valve assembly 50 is disposed in the open end of the pressure cylinder 30, and the discharge valve assembly 50 includes a valve plate 52, a discharge valve member 54 and a valve retaining member 56. The valve plate 52 is substantially dish-shaped and includes a pair of discharge holes 58 provided therein, and the valve plate 52 further includes a plurality of holes 60 'for accommodating most fixing members therein, and the @ 定 件 can discharge the same The valve member "is mounted on the valve plate 52 with the valve retaining member 56. As shown in Fig. 2 'The discharge member is a yellow sheet valve made of a heart | green material, and the discharge The reading member M abuts against the valve holding member 56 ′ having an isolated surface 62 and also includes a plurality of mounting holes 64 (only one of which is shown in FIG. 1) for receiving a plurality of fixed pieces, among which the fixing pieces Extending through the miscellaneous money arranged on the level 52 and the holes 66 arranged on the row of the member 54. The member 54 has a solitary notch that is mostly located by the row of the members in the row. 68 'The arc-shaped notches 68 help control the flexibility of the discharge valve member 54 and can cover the discharge holes during the suction state of the compressor operation and can flex during the compression phase of the shrink operation Keep away from the exhaust holes 58. The arc surface of the valve retaining member 56 has a contour that restricts the opening of the reed valve 54 to optimize stress and performance. = Valve sand and 卩 朴 holding member 56 form a suitable #machined record, so that the outer diameter of the closing plate 52 ㈣holding member 56 and the inner diameter of ^ can interfere with each other, thereby, the discharge can be 50%. And it is worn in the head 34 of the far-ear-body member 26, and the interference insert 20 1234609 with the diameter can seal and hold the valve plate 52 and the valve holding member 56. At the time of assembly, the piston 38 is held at a top dead center position and the discharge valve assembly 50 is cooled to a temperature that is low enough to thermally shrink the diameter of the discharge valve assembly 50. So 'it will fall freely into the cylinder 30. The exhaust valve assembly 50 abuts against the piston 38 until it becomes hot and large and presses and fits into the pressure cylinder 30. The forceful fitting can hold the exhaust valve assembly 50 and press at the pressure A seal is created between the cylinder 30 and the diameter of the discharge valve assembly 50. As shown in FIG. 3, when assembling the discharge valve assembly 50, a method of positioning the piston 38 within the pressure cylinder 30 is based on the bearing clearance between the connecting rod 40 and the crankshaft 22. A load is applied to the bearings in the opposite direction (by applying force F), so that the piston% is located slightly above the normal top dead center position. The gas force (when the reciprocating compressor is running) is pushed down against the plug 38, so that the load on the miscellaneous load is reversed and generated-a cold-active base approximately equal to the sum of the bearing assembly and the bearing gap assembly in operation. Clearance with the sampan. 15 20 It should also be noted here that, relative to cooling the valve assembly, choose the general cylinder to heat the cylinder before the cylinder, so that the diameter of the cylinder is enlarged, and the cylinder is returned to room temperature. You can get the interference in the assembly: In addition, 'two ways (heating the hemp and cooling the row_assembly) is also feasible. Furthermore, the history between the valve plate 52 and the cylinder 30 can be enhanced by using, for example, LOC measurement. Another embodiment is that the valve plate can be fixed in a blind hole with the same diameter as the diameter of the cylinder. However, this situation requires the operation of the valve to produce a "hole." The secondary machine is shown in Fig. 2. The top of the piston 38 is provided with a large number of air holes and tongues. The 1212609 is close to the top dead center and can be partially filled in the valve plate 5 2 of the discharge hole 5 s. The shape-complement columns 70, and the shape-compliance columns 70 can further reduce the gap between the living base 38 and the valve plate 52 at the top dead center to further increase the efficiency of the compressor. A single body member 26 includes a five bearing portion 72 in which the crank shaft 22 is housed, and the single body member 26 further includes an opening 74 provided in the bell portion 32, wherein the bell portion Part 32 is separated from the bearing portion 72 and the crank shaft 22 is housed therein. A crank case isolation seal member 76 is provided between the opening 74 and the crank shaft 22 to provide a large suction volume in the hollow section 44 and weaken the suction pulse. The suction gas entering through the suction inlet channel 10 17 is drawn into the motor cover 25 to the top of its upper edge and between the inside of the motor 盍 25 and the outer surface of the stator 20. Then, the suction gas goes upward Passing between the rotor and stator 20 and entering the hollow section 44 of the bell-shaped portion 32 of the body 28 and the stator 20, and the free volume between the motor 18 and the bell-shaped portion 32 can be used as One attracts 15 silencers. In addition, the sealing member prevents oil from flowing down the crank shaft from the main bearing and the connecting rod bearing above and into the suction gas. Furthermore, the aforementioned suction gas flow path can also prevent oil from entering the suction gas. Since the single body member 26 is constituted as a Zhuoyi prayer forming the body 28 containing the pressure cylinder 30 and the body 28 discharged from the head to 36A, 36B, the number of machined surfaces can be significantly reduced and A sealing member or gasket and a fixing member for connecting the head and the body are required. Please refer to Figs. 4A and 4B. The size and shape of the sealed housing 12 can support the motor 18 and the single body member 26 for two different applications. Oil temperature control is important in most hermetic compressors. If 12 1234609 oil is too hot, the lubricity will disappear and decomposition will occur. If the oil is too cold, the cold beam diluent will significantly affect the lubricity of the oil or adversely affect the reliability of the compressor. The temperature of the oil tank is extremely related to how the compressor is used. In applications with a high superheat to high pressure ratio, letting a small amount of heat drain into the oil helps to keep it in a safe temperature region, and this can be maintained by The head of the compressor is separated from the oil to achieve it. Applications with a low superheat to low pressure ratio can benefit from radiating heat to the oil, which can be achieved by immersing the head in the oil and operating the mechanism in the oil. Therefore, in the present invention, the size and shape of the sealed housing 12 can accommodate the motor 18 and the single body member 26, and the motor is disposed in the compressor oil tank, as shown in FIG. 4A, or The single body member 26 is installed in a 4 compressor oil tank, as shown in FIG. 4B.
