Abstract

An oil-air lubricant distributor with a tubular distributor body that includes an oil-air mixture inlet and a plurality of lubrication-point outlets for dispensing the oil-air mixture to at least one consumer, wherein the lubrication-point outlets are connected to the oil-air mixture inlet via line channels, and the line channels are provided with an oil-air mixture from a mixture distributor unit, the mixture distributor unit including a single oil inlet, a single air inlet, and a plurality of oil-air-mixture outlets, and wherein the oil-air mixture inlet is directly but releasably connected to the mixture distributor, and the oil-air-mixture outlets are directly but releasably fluidly connected to the line channels in the tubular distributor body.

First claim

What is claimed is:

1. An oil-air lubricant distributor, comprising:
a mixture distributor unit which provides an oil-air mixture to a tubular distributor body, the tubular distributor body includes a plurality of lubrication-point outlets for dispensing the oil-air mixture to at least one consumer;
the mixture distributor unit comprising a single oil inlet and a single air inlet for providing oil and air for mixing to form the oil-air mixture, the mixture distributor unit mixing the oil and air and communicating the oil-air mixture to the tubular distributor body via a plurality of oil-air-mixture outlets,
wherein the lubrication-point outlets are in fluid communication with the oil-air mixture provided by the mixture distributor unit via line channels, the mixture distributor unit is in fluid communication with the single oil inlet and the single air inlet;
wherein the single air inlet and the single oil inlet are directly but releasably connected to the mixture distributor unit, and the plurality of oil-air-mixture outlets are directly but releasably fluidly connected to the line channels in the tubular distributor body;
wherein the single air inlet for the mixture distributor unit is fluidly connected thereto via a plurality of air distributor channels, wherein the single oil inlet for the mixture distributor unit is fluidly connected thereto via a plurality of oil distributor channels,
wherein each of the plurality of oil-air-mixture outlets is respectively associated with one of the plurality of air distributor channels and with one of the plurality of oil distributor channels so that air is distributable via the air distributor channels from the single air inlet to the oil-air-mixture outlets, and oil is distributable via the oil distributor channels from the single oil inlet to the oil-air-mixture outlets;
wherein each of the oil distributor channels includes a metering unit configured to dispense a metered amount of oil into an air stream of one of the air distributor channels; and
wherein each metering unit includes a metering piston and a pumping piston.

2. The oil-air lubricant distributor according to claim 1 , wherein the mixture distributor unit is plugged-in, snapped-in, or screwed-in into the tubular distributor body.

3. The oil-air lubricant distributor according to claim 1 , wherein at least one of the air distributor channels includes a check valve and/or at least one of the oil distributor channels includes a check valve.

4. The oil-air lubricant distributor according to claim 1 , wherein the metering piston and the pumping piston are disposed in separate cylinder bores.

5. The oil-air lubricant distributor according to claim 4 , wherein the pumping pistons are disposed along a first circle having a first diameter and the metering pistons are disposed along a second circle having a second diameter greater than the first diameter, wherein the first circle is disposed concentrically within the second circle.

6. The oil-air lubricant distributor according to claim 5 , wherein the pumping pistons and metering pistons are disposed such that each metering piston is disposed circumferentially between two of the pumping pistons, and wherein an imaginary line alternatingly connecting centerpoints of the cylinder bores including the pumping pistons and centerpoints of the cylinder bores including the metering pistons is star-shaped.

7. The oil-air lubricant distributor according to claim 4 , wherein the mixture distributor unit is cylindrical, and the metering units are disposed circumferentially about the mixture distributor unit.

8. An oil-air lubricant distributor, comprising:
a mixture distributor unit which provides an oil-air mixture to a tubular distributor body, the tubular distributor body includes a plurality of lubrication-point outlets for dispensing the oil-air mixture to at least one consumer;
the mixture distributor unit comprising a single oil inlet and a single air inlet for providing oil and air for mixing to form the oil-air mixture, the mixture distributor unit mixing the oil and air and communicating the oil-air mixture to the tubular distributor body via a plurality of oil-air-mixture outlets,
wherein the lubrication-point outlets are in fluid communication with the oil-air mixture provided by the mixture distributor unit via line channels, the mixture distributor unit is in fluid communication with the single oil inlet and the single air inlet;
wherein the single air inlet and the single oil inlet are directly but releasably connected to the mixture distributor unit, and the plurality of oil-air-mixture outlets are directly but releasably fluidly connected to the line channels in the tubular distributor body;
wherein the single air inlet for the mixture distributor unit is fluidly connected thereto via a plurality of air distributor channels, wherein the single oil inlet for the mixture distributor unit is fluidly connected thereto via a plurality of oil distributor channels,
wherein each of the plurality of oil-air-mixture outlets is respectively associated with one of the plurality of air distributor channels and with one of the plurality of oil distributor channels so that air is distributable via the air distributor channels from the single air inlet to the oil-air-mixture outlets, and oil is distributable via the oil distributor channels from the single oil inlet to the oil-air-mixture outlets;
wherein each of the oil distributor channels includes a metering unit configured to dispense a metered amount of oil into an air stream of one of the air distributor channels; and
wherein at least one of the air distributor channels includes a check valve and/or at least one of the oil distributor channels includes a check valve;
wherein the mixture distributor unit is plugged-in, snapped-in, or screwed-in into the tubular distributor body;
wherein each metering unit includes a metering piston and a pumping piston.

9. The oil-air lubricant distributor according to claim 8 , wherein the tubular distributor body and/or the mixture distributor unit includes at least one positioning aid configured to ensure a positioning of the mixture distributor unit in the tubular distributor body such that the line channels of the tubular distributor body are fluidly connected to the oil-air-mixture outlets of the mixture distributor unit.

10. The oil-air lubricant distributor according to claim 8 , wherein the metering piston and the pumping piston are disposed in separate cylinder bores.

11. The oil-air lubricant distributor according to claim 10 , wherein the pumping pistons are disposed along a first circle having a first diameter and the metering pistons are disposed along a second circle having a second diameter greater than the first diameter, wherein the first circle is disposed concentrically within the second circle.

12. The oil-air lubricant distributor according to claim 11 , wherein the pumping pistons and metering pistons are disposed such that each metering piston is disposed circumferentially between two of the pumping pistons, and wherein an imaginary line alternatingly connecting centerpoints of the cylinder bores including the pumping pistons and centerpoints of the cylinder bores including the metering pistons is star-shaped.
