Benefits of technology
[0009]Generally, a pre-lubrication system is described herein and is provided to augment the normal lubrication system of an air compressor. The pre-lubrication system is generally intended to be operated just prior to operation of the air compressor to ensure that pressurized oil is available during start-up of the air compressor. In one embodiment, air compressor pre-lubrication system comprises an oil pump, a priming tank, and a control valve. The oil pu
Problems solved by technology
In particular, when the compressor is shut down, the oil pressure within the compressor quickly bleeds back to an oil sump.
For compressor applications where hundreds of starts may be required each month, the accumulated result of periods during startup without full lubrication may result in reduced compressor life.

Embodiment Construction
[0018]For purposes of the description hereinafter, spatial orientation terms, as used, shall relate to the referenced embodiment as it is oriented in the accompanying drawing figures or otherwise described in the following detailed description. However, it is to be understood that the embodiments described hereinafter may assume many alternative variations and configurations. It is also to be understood that the specific devices, features, and components illustrated in the accompanying drawing figures and described herein are simply exemplary and should not be considered as limiting.
[0019]Referring to FIG. 1, an air compressor pre-lubrication system 20 is schematically shown. Pre-lubrication system 20 is provided to augment the normal lubrication system of an air compressor 45 and is intended to be operated just prior to operation of the air compressor 45 to ensure that pressurized oil is available during start-up of the air compressor 45. Without pre-lubrication system 20, during a...

The air compressor pre-lubrication system includes an oil pump, a priming tank, and a control valve. The oil pump is connected to an oil sump and includes a discharge line connected to an air compressor. The priming tank is connected to the oil pump to receive pressurized oil. The control valve is provided in an outline line connected to the priming tank and is further connected to the oil pump discharge line. The priming tank is configured to maintain a charge of oil from the oil pump and selectively release the charge of oil through actuation of the control valve. An auxiliary pre-lubrication oil pump may replace the priming tank. The pre-lubrication oil pump is connected to the oil sump and is fluidly coupled to the discharge line leading to the air compressor.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an air compressor and, more particularly, to a pre-start lubrication system for an air compressor.[0003]2. Description of Related Art[0004]Often during startup of a compressor there is a period of time that the lubrication system of the compressor will not have full pressure. In particular, when the compressor is shut down, the oil pressure within the compressor quickly bleeds back to an oil sump. With the passageways of the lubrication system emptied of oil, when the compressor is restarted, it will run without lubrication or with partial lubrication for a period of time until the passages are once again filled and pressurized. This period of time will vary based on several factors.[0005]Many compressors were originally designed for continuous operation. However, since the addition of electric motor drive, start / stop operation has become the standard method of control. For compressor ap...
