Abstract

In a refrigeration compressor having at least one piston-cylinder arrangement (36, 38) therein for compresssing gaseous refrigerant, an elongated tube (68) extending upwardly from a lubricant passage (60) in the crankshaft (18) for slinging oil radially, outwardly therefrom, and a lubricant deflector (82) upstanding from the cylinder head (48) to deflect slung oil over exterior surfaces of the cylinder head for conducting heat energy therefrom.

The end B 8 is connected to the oil pump 9 located in the oil pan 10. The 8 B channel 11 is connected on one side to the oil pump 9, on the other side is connected to the inclined channel 12 of the crank 7, the upper end of which is connected to the elongated hollow body 13, The body 13 is connected to B 8 and has an opening 14 for ejecting the lubricant agent. The means 15 for reflecting and directing the ejected lubricant agent is mounted on the head 4 and is integral with it.

15 there is a groove forming with the surface of the head 4 a hole for the passage of the lubricant agent "In the body 13 from the side opposite the axis of rotation B 8, a radial hole 17" is made. The upper portion of the body 13 is angled to the axis of rotation B 8 in the direction from the axis to the casing 1 "The location of the hole 17 is selected based on the height of the location of the means 15 and the path of movement of the ejected lubricant agent about 2 ° C.

The invention relates to hermetic refrigeration compressors, and more specifically to an oil distribution system for compressors adapted to divert thermal energy from the cylinder head in the compressor housing.

The purpose of the invention is to increase the cooling efficiency.

In Fig "1 shows the proposed device, the cut | in fig. 2 - the same, top view; in FIG. 3, the same. left side view of the top of the device; Fig 4 - cylinder head, internal view; Fig 5 - section A-A on FIG4; Fig 6 - view of the elongated hollow body 5

The hermetic compressor in combination with the oil distribution system contains a hermetic casing 1, frame 2 with cylinder 3 located on it, sealed head 4, piston 5 installed in cylinder 3 and connected with drive element b with crank 7 of vertical crankshaft 8 which is connected to the oil pump 9, located in the oil pan 10, while in the crankshaft 8 the channel 1 is connected with. one side with an oil pump 9, ac another with an inclined channel 12 in crank 7, the upper end of which is connected with an elongated hollow body 13 connected to the crankshaft 8 and containing an opening 4 for ejecting a lubricant and the direction of the ejected lubricating agent. A means 5 for reflecting and directing the ejected lubricating agent is mounted on the head 4 of the cylinder 3 and is integral with it, while the means 15 for reflecting and guiding comprises a groove forming an opening 16 with the surface of the head to pass the lubricating agent to the cylinder 4.

In the elongated hollow body 13 from the side opposite to the axis of rotation of the crankshaft 8, a radial hole 17 is made,

The upper portion of the hollow body 13 is located at an angle to the axis of rotation of the crankshaft 8 in the direction from the axis to the casing 1 o

During compressor operation, the lubricant from the oil sump 10 is supplied by the oil pump 9 successively to the channel 11 of the vertical crankshaft 8, the inclined channel 12 in the crank 7, the hollow body 13, and from there through the hole 14 under the action of centrifugally force is thrown onto the inner surface of the leather 1 and , the stack along it into the oil pan 10, is cooled about the length of the hollow body 13 is chosen based on the location of the hole 14, preferably over all elements of the compressor; , and the angle of inclination - depending on the desired angle of spray lubricant agent

Simultaneously with spraying onto the surface of the casing, 1 part of the oil from the hollow body 13 through the radial opening 17 is thrown into the cavity of the casing, gets onto the means 15 to reflect and guide the lubricant agent and then flows through the opening 16 along the surface of the head 4 to cool it. To ensure this property of the proposed device
