| 32 | Oil-Injected Compressor with a Temperature Switch | US11908068 | 2006-03-08 | US20090041589A1 | 2009-02-12 | Konrad Liebert; Michael Schmid; Nils Zieglgansberger; Karl Hering |

At least one non-self-resetting additional temperature switch is provided in the internal area of the oil separating device, which immediately switches off the compressor unit following a fire or an explosion of the compressed air, which contains oil, and which is contained in the oil separating device. | ||||||
| 33 | Vane Pump | US11884217 | 2006-01-31 | US20080159896A1 | 2008-07-03 | Yoshinobu Kishi; Kikuji Hayashida; Kiyotaka Ohtahara |
| After a vane 4 passes an oil supply groove 13 formed in a housing 2 due to rotation of a rotor 3, a branch passage 12a of an oil supply passage formed in a shank 3B of the rotor communicates with the oil supply groove 13, then a lubricating oil flows into a pump room 2A through the oil supply groove 13. Then, owing to a differential pressure between a first space A and a second space B, the lubricating oil which flowed into the first space is spouted in the direction opposite to the rotational direction, being blown against the vane which subsequently passes, thereby sealing a gap between the vane and the pump room can be rapidly carried out.Even if the lubricating oil is not sufficiently fed into the pump room, a vane pump can rapidly exert its original performance. | ||||||

| 36 | Scroll machine with overheating protection | US313067 | 1994-12-09 | US5527158A | 1996-06-18 | Jeffery D. Ramsey; Jean-Luc Caillat; Sunil S. Kulkarni |
| A thermally responsive valve assembly (134) for scroll motorcompressor high temperature protection, which causes a high-side to low-side leak when excessive discharge gas temperatures are encountered, thereby causing the motor protector (35) to trip and de-energize the motor. The valve assembly (134) includes means motor ducting (200) the excessive temperature discharge gas to the lower portion of the motor/compressor shell (10) to the motor to circulate the high temperature gas throughout the motor cavity. The excessive temperature discharge gas heats the motor stator (20) and windings (32) which will in turn cause the motor protector (35) to trip and de-energize the motor. | ||||||
| 37 | Reverse phase and high discharge temperature protection in a scroll compressor | US811777 | 1991-12-20 | US5186613A | 1993-02-16 | Peter A. Kotlarek; John R. Moilanen; Mark W. Harrison |
| A low side scroll compressor is protected from both the potentially damaging effects of improper electrical hookup and the development of high discharge temperatures by the disposition of a valve member in a passage which communicates between the suction pressure portion and a discharge pressure portion of the compressor. The valve operates to permit the flow of gas from the suction to the discharge pressure portion of the compressor through a protective passage when the compressor is caused to run backwards due to miswiring so as to avert damage to the scroll members. The valve permits the flow of gas from the discharge to the suction pressure portion of the compressor through the protective passage when the temperature of the discharge gas produced by the compressor is caused to exceed a predetermined temperature. The resulting flow causes the compressor motor to de-energize. | ||||||
