Embodiment Construction
[0014] Figure 1 highlights the structural overview of the "no backlash" design of a crankshaft driven compressor.
[0015] As shown in Fig. 2, the piston 5, which is doing the compression and exhaust work, squeezes all the compressed high-pressure gas into the high-pressure zone H, and then it continues to rush out of the cylinder 6 against the exhaust valve plate 3, and Enter high pressure zone H. At this time, the geometric space ("clearance") between the piston 5, the conical suction valve block 4 and the exhaust valve plate 3 is not difficult to reach extremely close to "zero", or even equal to "zero". . The stroke of the piston 5 rushing out of the cylinder 6 can usually be controlled at about 1 / 10 of its effective suction stroke length.
[0016] As shown in Figure 3, when the piston 5 retreated into the cylinder 6 completely, the exhaust valve plate 3 positioned by the spring 2 would naturally allow it to be driven by high air pressure to seal the top of the cylinder 6...
