权利要求: 1. Rotary positive displacement machine package(1) with a dry-running, twin-shaft rotary positive displacement machine (100) and a lubricant supply device (10), wherein the lubricant supply device (10) comprises an electrically driven lubricant pump (14), characterised in that the lubricant pump (14) can be operated with a control voltage of the rotary positive displacement machine package(1), the control voltage being < 50 V and the rotary positive displacement machine package having a control voltage power supply unit, which provides an electrical supply to a control device of the rotary positive displacement machine package and the lubricant pump.2. Rotary positive displacement machine package(1) according to claim 1, characterised in that the control voltage is DC voltage.3. Rotary positive displacement machine package(1) according to claim 1 or 2, characterised in that the lubricant pump (14) is a positive displacement pump.4. Rotary positive displacement machine package (1) according to one of the preceding claims, characterised in that the lubricant pump (14) is an oscillating piston pump.5. Rotary positive displacement machine package(1) according to claim 4, characterised in that the lubricant pump (14) is an oscillating piston pump with an upstream pulse-width modulator (21).6. Rotary positive displacement machine package (1) according to one of claims 1-3, characterised in that the lubricant pump (14) is a gear pump.7. Rotary positive displacement machine package(1) according to one of the preceding claims, characterised in that the rotary positive displacement machine package(1) is designed for a connected load of ≤ 110 kW, preferably ≤ 60 kW.8. Rotary positive displacement machine package(1) according to one of the preceding claims, characterised in that the control voltage is < 30 V.9. Rotary positive displacement machine package (1) according to one of the preceding claims, further comprising a lubricant cooler (15), which is arranged in particular on an outlet side of the lubricant pump (14).10. Rotary positive displacement machine package(1) according to one of the preceding claims, further comprising a lubricant filter (13), which is arranged in particular on an inlet side of the lubricant pump (14).11. Rotary positive displacement machine package(1) according to one of the preceding claims, comprising a supply line (11) for conveying a lubricant from the lubricant pump (14) to a bearing and/or a synchronisation gear of the rotary positive displacement machine (100) and a return line (12) for conveying a lubricant from a bearing and/or a synchronisation gear of the rotary positive displacement machine (100) to the lubricant pump (14).12. Rotary positive displacement machine package(1) according to one of the preceding claims, wherein the rotary positive displacement machine (100) is a twin-shaft screw compressor.13. Use of a lubricant pump (14) for a lubricant supply of a dry-running rotary positive displacement machine (100), wherein the lubricant pump (14) is operated with a control voltage of a control voltage power supply unit of the rotary positive displacement machine package(1), wherein the control voltage is < 50 V, preferably < 30 V.14. Use according to claim 13, wherein the lubricant pump (14) is operated with direct current.15. Use according to one of claims 13-14, wherein the lubricant pump (14) is an oscillating piston pump, preferably an oscillating piston pump with an upstream pulse-width modulator (21).
