Abstract
In a refrigeration compressor having at least one piston-cylinder arrangement therein for compressing gaseous refrigerant, an elongated, tube extending upwardly from a lubricant passage in the crankshaft for slinging oil radially, outwardly therefrom, and a lubricant deflector upstanding from the cylinder head to deflect slung oil over exterior surfaces of the cylinder head for conducting heat energy therefrom.
Claims9
In combination with a compressor including a hermetically sealed housing having a crankcase therein with a cylinder disposed in said crankcase and a sump in a bottom portion thereof, a vertically disposed crankshaft rotatably received in said crankcase and having a piston operably connected thereto and disposed in said cylinder, a cylinder head, said crankshaft having pump means connected to its bottom portion and disposed in said sump for pumping lubricant from said sump upwardly through a lubricant passage in said crankshaft, a lubricant distribution system comprising:
- a generally elongated hollow body connected to said rotatable crankshaft and in communication with said lubricant passage and having an opening through which lubricant is thrown radially outwardly upon rotation of said crankshaft, and
- means on and vertically upstanding from said cylinder head for directing a portion of the lubricant slung by said generally elongated hollow body to said cylinder head to conduct heat energy therefrom.
In combination with a compressor including a hermetically sealed housing having a crankcase therein with a cylinder disposed in said crankcase and a sump in a bottom portion thereof, a cylinder head, a vertical crankshaft rotatably received in said crankcase and having a piston operably connected thereto and disposed in said cylinder, said crankshaft having centrifugal pump means connected to its bottom portion and disposed in said sump for pumping lubricant from said sump upwardly through a lubricant passage in said crankshaft, said crankshaft having means connected to its upper portion for slinging lubricant radially outwardly therefrom, a lubricant deflector comprising:
- means on and vertically upstanding from said cylinder head and in direct thermal contact with said cylinder head for catching a portion of the lubricant slung by said slinging means to conduct heat energy from said cylinder head.
In a compressor including a hermetically sealed housing having a crankcase therein with a cylinder disposed in said crankcase and a sump in a bottom portion thereof, a vertical crankshaft rotatably received in said crankcase and having a piston operably connected thereto and disposed in said cylinder, a cylinder head, said crankshaft having pump means connected to its bottom portion and disposed in said sump for pumping lubricant from said sump upwardly through a lubricant passage in said crankshaft, a lubricant distribution system comprising:
- a generally hollow body connected to said crankshaft and in communication with said lubricant passage and having an upper end opening through which lubricant is thrown against the housing, said body including a side opening through which lubricant is thrown radially outwardly as the crankshaft rotates, and heat sink means on and vertically upstanding from said cylinder head and in direct thermal contact therewith for catching at least a portion of the lubricant thrown out of said side opening to thereby conduct heat away from said cylinder head to the lubricant.
