Embodiment
As shown in Figure 1, a kind of screw compressor of adjustable interior volume ratio, comprise compressor housing 1, exhaust end housing 2, between compressor housing 1 and exhaust end housing 2, be provided with screw rotor 3, on compressor housing 1, be provided with the intakeport (not shown), on exhaust end housing 2, be provided with the axial exhaust port (not shown) and reach radially relief opening 4; This compressor also comprises the activation part of being made up of interior volume specific ratio adjusting slider 12 and capacity regulating slide block 13, and radially relief opening 4 is on capacity regulating slide block 13; On compressor housing 1, be provided with cylinder body 5, in cylinder body 5, be provided with piston 6, be provided with filler opening 10, be provided with three oil outlets 9 along its axial direction in the fuel-displaced side of cylinder body 5 in the oil-feed side of cylinder body 5, one end of piston rod 7 is connected with piston 6, and the other end is connected with interior volume specific ratio adjusting slider 12; On exhaust end housing 2, the opposition side of aforementioned cylinder body 5 is provided with subsidiary cylinder 11, in subsidiary cylinder 11, also be provided with piston 6, be respectively equipped with filler opening 10 and oil outlet 9 in the both sides of subsidiary cylinder 11 upper pistons 6, this piston 6 is connected with capacity regulating slide block 13 by piston rod 7.
Opposite side at interior volume specific ratio adjusting slider 12 and capacity regulating slide block 13 is provided with endoporus, be provided with helical spring 14 between interior volume specific ratio adjusting slider 12 and the capacity regulating slide block 13, this helical spring 14 inserts in the endoporus, and in helical spring 14, be provided with directional post 15, be provided with spiracle 8 on interior volume specific ratio adjusting slider 12, the both sides of interior volume specific ratio adjusting slider 12 communicate by this spiracle 8.
