Abstract

Abstract A lubricating system for rotary piston compressors, in which the lubricating oil passes from a storage container in predetermined quantities to the lubricating points. The compression chamber of the rotary piston compressor, which compression chamber is under alternating pressure is through an opening in communication with a diaphragm piston pump. This pump draws lubricating oil from the storage container and conveys it to a rotating spray disc connected to the shaft of the rotary piston compressor. The lubricating oil centrifuged by the spray disc or splash disc passes to a minor part to wires within the effective range of the spray or splash disc, which wires are arranged at a decline to the horizontal plane and lead to the lubricating point.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 180 words
In combination in a rotary piston compressor: main housing means, lateral housing means adjacent and laterally connected to said main housing means, rotary piston means rotatable within said main housing means and with said main housing means and said lateral housing means defining a compression chamber, a reservoir for receiving and storing a lubricant, a diaphragm piston pump arranged in said lateral housing means, first conduit means establishing communication between said reservoir and said diaphragm piston pump, second conduit means leading from said compression chamber to said diaphragm piston pump, bearing means arranged within said lateral housing means, shaft means rotatably journalled in said bearing means and eccentrically connected to said rotary piston means, splash disc means fixedly and eccentrically connected to said rotary piston means and rotatable therewith, said diaphragm piston pump being operable to draw a lubricant from said reservoir and convey lubricant to said splash disc means, and wire Means arranged within the sphere of action of said splash disc means and while being inclined relative to a horizontal plane leading to a point to be lubricated.
Claim 2
Dependent Claim 180 words
In combination in a rotary piston compressor: main housing means, lateral housing means adjacent and laterally connected to said main housing means, rotary piston means rotatable within said main housing means and with said main housing means and said lateral housing means defining a compression chamber, a reservoir for receiving and storing a lubricant, a diaphragm piston pump arranged in said lateral housing means, first conduit means establishing communication between said reservoir and said diaphragm piston pump, second conduit means leading from said compression chamber to said diaphragm piston pump, bearing means arranged within said lateral housing means, shaft means rotatably journalled in said bearing means and eccentrically connected to said rotary piston means, splash disc means fixedly and eccentrically connected to said rotary piston means and rotatable therewith, said diaphragm piston pump being operable to draw a lubricant from said reservoir and convey lubricant to said splash disc means, and wire Means arranged within the sphere of action of said splash disc means and while being inclined relative to a horizontal plane leading to a point to be lubricated.
Claim 3
Dependent Claim 30 words
An arrangement according to claim 1, in which said second conduit means is arranged in that lateral wall portion of said lateral housing means which partially defines said compression chamber.
Claim 4
Dependent Claim 17 words
An arrangement according to claim 1, in which a counterweight is associated with said splash disc means.
Claim 5
Dependent Claim 24 words
An arrangement according to claim 1, in which said wire means are radially spaced from the axis of rotation of said splash disc means.
Claim 6
Dependent Claim 17 words
An arrangement according to claim 1, in which said wire means are round wires of different diameters.
