Embodiment Construction

[0017] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are shown in the accompanying drawings.

[0018] see figure 1 , in this embodiment of the invention, an oil-lubricated air compressor 100 is discussed. In further embodiments, the principles of the invention are implemented in various other mechanical devices including engines (particularly small motors below 20 hp (20 horsepower) or lawnmower type engines), oil pumps, etc. where efficient Lubricant status and quantity determined. For example, the compression pump included in the compressor is a reciprocating piston pump disposed at least partially in the cylinder head for compressing air from a first pressure to a second pressure. It should be understood that various pump configurations are possible and it is the intent of this disclosure to cover and encompass such variations.

[0019] Compressor 100 may have a crankcase 102 or other suitable housing. Crankcase 10...

Abstract

A mechanical device including a crankcase (102) and reservoir plug (112) suitable for detecting the quantity of lubricant is disclose. In an aspect, the reservoir plug (104) is configured to permit observation of the interior of the plug / crankcase (102) in order to observe the level of contained lubricant. The drain hole (112) for receiving the plug (104) is disposed to encompass the range between the maximum acceptable lubricant level and the minimum acceptable lubricant level. The plug (104) may include a main body portion and transparent portion for permitting observation of fluid, disposed on a second side, from a first side of a sealing interface.

Description

[0001] related application [0002] Pursuant to 35 U.S.C § 119(e), this application claims priority to U.S. Provisional Application 60 / 580,825, filed June 18, 2004, entitled: "Reservoir Seal with Liquid Level Indicator," This application is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to compressors, and more particularly to a reservoir seal for a lubricated crankcase. Background technique [0004] Many mechanical devices have crankcases that house the mechanical parts and require lubrication to minimize wear on the moving parts. During operation, the lubricant contained in the oil sump or the lower part of the crankcase is thrown or splashed onto the parts that need to be lubricated. Key factors in minimizing component wear include ensuring the proper amount of lubricant and preventing lubricant degradation / contamination due to water, particulate matter, etc. For small engines and machinery such as pum...
