Oiling agent metering system 18 can comprise calotte 100, cap 102, packing ring 104, sealing plate 106 and with the lubricant pipe 108 of oiling agent metering system 18 and oiling agent storage tank 36 fluid coupled.Oiling agent metering system 18 can be fixed on second bearing 56 via a plurality of bolts 110.
Continuation will describe the operation of compressor 10 in detail with reference to accompanying drawing 1-4.Electric motor assembly 14 energisings make live axle 50 rotations, and live axle 50 is operate compressor structure 16 again.As mentioned above, compressing mechanism 16 makes working fluid cycles pass through refrigeration system or heat pump.Between compressor 10 on-stream periods, the working fluid of relatively low pressure is via sucking gas access pipe joint 22 inspiration suction chambers 43.The operating on low voltage fluid is inhaled into compressing mechanism 16 and is compressed into higher relatively head pressure from suction chamber 43.Then, working fluid escapes and enter from compressing mechanism 16 by discharge route 44 and discharges in the chamber 34.Oiling agent in the compressing mechanism 16 can enter with the working fluid mixing and with working fluid and discharge in the chamber 34.Be arranged in the lubricant separator 156 (Fig. 2) of discharging in the chamber 34 from filtering from working fluid or separating some or all oiling agents.In case separate with working fluid, oiling agent can fall in the oiling agent storage tank 36 from lubricant separator owing to gravity.In some structure, lubricant separator 156 can be arranged in frame set 12 outsides, and provides oiling agent to the exterior lubricant storage tank (not shown) that is arranged in outside the frame set 12.
As shown in Figure 2, the oiling agent import 124 of calotte 100 is communicated with suction chamber 43 fluids via radial hole 134, measuring hole 64, axial bore 62, eccentric opening 63 and lubricant delivery hole 66.Therefore, the pressure reduction between high side oiling agent storage tank 36 and the suction chamber 43 makes the high pressure lubricant that is stored in the oiling agent storage tank 36 flow through the calotte 100 that lubricant pipe 108 flows to oiling agent metering system 18.Oiling agent flows through pipe joint 154 and flows into oiling agent import 124 from lubricant pipe 108, then flows in the high pressure lubricant reservoir 143 that is arranged between calotte 100 and the cap 102.The relative high pressure lubricant that is arranged in the high pressure lubricant reservoir 143 can urge cap 102 vertically so that edge 141 joint rings 104 of cap 102.
As mentioned above, the gap between the internal diameter of the recess 118 of the external diameter 136 of cap 102 and calotte 100 allows cap 102 to move diametrically or " floating " with respect to calotte 100.Like this, the rotationally symmetric axis of the removable recess 142 with " automatically-aim at " cap 102 of cap 102 and the spin axis of live axle 50.This automatic alignment characteristics provides more firm sealing between the external diameter of the internal diameter 138 of cap 102 and live axle 50.Because live axle 50 is axially placed in the middle the recess 142 of cap 102 in, therefore can minimize the gap between the external diameter of the internal diameter 138 of cap 102 and live axle 50, minimize the oiling agent leakage between the two thus.Minimized oiling agent between the internal diameter 138 of the cap 102 that brings owing to the automatic aligning of recess 142 and live axle 50 and the external diameter of live axle 50 is revealed the position of guaranteeing that oiling agent is transported to be needed, such as, such as main bearing body 54 and second bearing, 56 places.In addition, the external diameter of the live axle 50 that causes owing to the rotating eccentricity degree and the friction of the part between the recess 142 can be minimized or eliminate, minimize or eliminate concentrated wear thus and prolong these parts life-span, improve the efficient of these parts.
As mentioned above, utilize the hydrodynamic pressure of high pressure lubricant reservoir 143 in-lubricants to make the 141 biasing ground, edge of cap 102 guarantee that against packing ring 104 measuring hole 64 and radial hole 134 axially align and allow cap 102 with respect to calotte 100 radial motions.On the contrary, if against packing ring 104, then bolt or other fastening piece are needed puts on the cap 102 so that edge 141 and will stop or limit the radially automatically aligning of cap 102 with respect to live axle 50 against the confining force of packing ring 104 sealings via bolt or other fastening piece biasing ground at edge 141.
