A combined power steering pump and vacuum pump assembly Is disclosed wherein a vented reservoir 18 Is connected to receive discharge air from the vacuuacn pump 28 as well as supply fluid for circulation by and lubrication of the power steering pump 10. A sealing arrsngement 44 seals the vacuum pump from the power steering pump when the pumps are stopped, but provides limited delivery of fluid from the power steering pump to the vacuum pump when the pumps are running, whereby the fluid in the power steering system is prevented from draining into the vacuum pump when stopped but is delivered thereto when running to lubricate same and is then delivered with the discharge air to the reservoir, so that there is no loss of fluid from the power steering system in lubricating the vacuum pump. |

| The present invention relates to a technology of efficiently cooling a vacuum pump that produces a vacuum in a process chamber of a semiconductor manufacturing facility. The present invention provides a new type of vaccum pump cooling method that keeps the internal temperature of a vacuum pump at a predetermined level by circulating oil through rotors of the vacuum pump, such that it is possible to prevent a rapid increase in the temperature of the vacuum pump and smoothly lubricate bearings at the early stage of operation, whereby it is possible to ensure stability when performing processes and operating the pump and economically maintain the facility. | ||||||

| The present invention is directed to an apparatus for determining vane wear in rotary sliding vane pumps that operate using slideable vanes, while the pump is in operation. The invention includes a structure that allows a predetermined amount of leakage from a pumping chamber after a predetermined amount of vane length is worn away. The leakage produces a decrease in pump efficiency that is indicated by an indicating device. The indicating device serves to warn that an amount of vane wear has occurred that indicates pump inspection is warranted. The invention also includes a view port formed in the pump housing to allow inspection of the vanes without having to disassemble the pump. | ||||||

| A plug for plugging a first port and blocking insertion of a second plug into a second port of a fluid system. The plug includes a threaded plug portion and a blocking stem portion extending from the threaded plug portion. The stem portion projects into the second port and blocks insertion or mounting of a second plug and thereby keeps the second port unplugged. In a disclosed embodiment, the plug is mounted into the return port of an oil pump unit of an oil burner to block bypassed flow from returning to the local reservoir of the oil pump unit. This prevents two plugs from being inadvertently mounted that could otherwise block all bypass flow in the pump unit and cause excess pressure build ups and blown seals. | ||||||
