Abstract

PURPOSE:To make it possible to prevent the damage such as seizure of a compressor by hermetically forming an oil reservoir chamber while fitting it to a driving shaft and supplying oil to a slide part of a swash plate disc by making use of its rotation. CONSTITUTION:An oil reservoir (b) is formed in the partition wall (b) of a cavity part by its fitting to a driving shaft 1. An oil passage equipped with an oil (d) discharge port 5 is provided radially from the oil reservoir chamber (b) in the outer peripheral direction of a swash plate disc 2 excepting the thrust bearing side. Accordingly, the swash plate disc 2 is turned by the driving force from the outside, and the oil (d) is supplied by the centrifugal force thereof to a slide part among a shoe 7 and a rolling ball 8, etc., intervened between the thrust bearing C and the piston G and the swash plate disc 2, allowing the damage such as the seizure of a compressor to be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a swash plate disk mounted on a rotary compressor.

Conventionally, the swash plate disk was installed between the front and rear cylinders, straddling the piston, and reciprocated the histones by rotation, but with the conventional oil distribution method, each sliding part was completely covered As a result, the sliding parts of the compressor were worn out and burnt during initial operation and other conditions. The present invention is intended to eliminate the above-mentioned drawbacks and to maintain the advantages of a crankshaft type compressor. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a swash plate disk manufactured by a simple and effective manufacturing method.
The objective is to improve the performance of the compressor by a configuration suitable for actual use. Embodiments of the invention will therefore be described with reference to the drawings. In FIGS. 1 to 3, a swash plate disk 2 is fixed around a drive shaft 1, and an oil reservoir is formed by fitting the swash plate disk 2 to the drive shaft 1. Driving shaft l from oil sump chamber
In other words, the oil d is supplied and sucked into the swash plate disk 2 and the thrust bearing C that abuts on both sides thereof.

The outlet port 5 and the side wall e of the swash plate disc 2 from the oil reservoir chamber
A discharge port 5□ is drilled in the direction following the oil reservoir chamber, and a discharge port 5. An oil passage 6 is drilled.

The oil passages 6 and the like in which the discharge 1 of the oil/f d and the like are provided are provided radially in the direction of the outer peripheral edge f of the swash plate 2 through the oil reservoir chamber, except for the thrust bearing side. According to the present invention,
The swash plate disk 2 rotates due to the driving force from another source, and the swash plate disk 2 rotates due to the centrifugal force of the thrust bear link c1 and the rolling ball 8, etc., which are interposed between the piston g.
Completely supply oil d to the sliding parts. The manufacturing method of the oil distribution device which is a feature of the present invention is as follows:
etc. can be manufactured by the die-gusting method, sintered alloy, and QIJ formation such as j;
Create lJ. The above steps and others can be easily carried out by a certain person. As shown in FIG.
The oil reservoir is formed in a hermetically sealed manner by the stop, and due to their rotation, the oil supply to the swash plate disk 2, especially the histone g, is completely sealed. This prevents compressor wear and tear and improves the performance of the compressor.Furthermore, it depends on the oil distribution device.Figure 1 is a cutaway side view of the present invention, and Figure 2 is a front view. , FIG. 8 is a diagram showing the operating state of the compressor.
