Embodiment Construction

[0019] Reference is made to said drawings, which show an air / oil lubricating arrangement, indicated generally by the reference number 1 .

[0020] The device includes a lubricant fluid storage container 2 . The container comprises a pipe connecting the outlet of the container to the suction of the high-pressure pump 6 .

[0021] A conduit supplies lubricant fluid from the container 2 to the suction 7 .

[0022] The pump may be of known type and comprises a high pressure outlet and is capable of pumping the oil and lubricant contained in the container to a pressure between 1 bar and 10 bar.

[0023] In an alternative embodiment, the lubricant contained in the container can be pressurized by suitable means other than a pump (eg, pneumatically) to supply the pressurized lubricant to the delivery conduit.

[0024] The transfer pipeline feeds one or more air / oil mixing modules M.

[0025] Each modular element M has a first channel 73 for pressurized oil and a second channel 72 f...

Abstract

A minimal lubrication device (1) comprising a lubricant fluid storage reservoir (2) and a pump (6) for said lubricant, said pump (6) being a high pressure pump with a delivery side connected to at least one modular element (M) arranged to mix a compressed air flow with said lubricant, said modular element (M) presenting a mixer element fed with a compressed air flow into which an outlet opens of a needle flow regulator fed by the lubricant originating from the pump. The module (M) comprises a compensator device which maintains the oil quantity dispensed by the flow regulator constant even if the pressure on the user side changes.

Description

technical field [0001] The present invention relates to a minimum air / oil lubrication device. [0002] More specifically, the present invention relates to modular devices. Background technique [0003] Air / oil lubrication represents a relatively recent reality and is the result of the introduction of advanced technologies that are mainly applied in the field of dry machining. Traditional sprinkler systems were also replaced due to negative environmental impact. [0004] Basically, lubrication takes place by supplying a continuous flow of air providing delivery means for oil delivery as far as the lubrication point and cooling means for the elements to be lubricated and the lubrication system. [0005] Oil injected into the air continuously or at even intervals covers the surface to be lubricated, thus reducing friction and wear. [0006] An air / oil lubricating device now includes an oil container pressurized by a compressed air source. The oil pressurized in this way is ...
