Embodiment Construction

[0023] Reference is made to said drawings, which show an air / oil lubrication device generally indicated by the reference number 1 .

[0024] It comprises a lubricant fluid reservoir 2 supported by a plate 3 to which the device is fixed. The reservoir comprises an element (for example of the float type) for sensing the level of fluid in the reservoir and a filter 5 associated with an orifice for feeding lubricant into the reservoir. This fixed plate 3 comprises a duct connecting one end of the reservoir to the suction port of a high pressure pump 6 fixed below the plate.

[0025] A conduit supplies lubricant fluid from the reservoir 2 to the suction port 7 .

[0026] The high pressure pump 6 comprises a first hydraulic block 6A for pumping fluid via the cylinder 9 and a second pneumatic block 6B for operating the cylinder 9 .

[0027] The cylinder 9 of the hydraulic block slides in the compression chamber. The center of the compression chamber 10 includes a fluid supply port...

Abstract

A minimal lubrication device comprising a storage reservoir for a lubricant fluid and a pump for said lubricant, said pump being of high pressure type with its delivery port connected to at least one modular element adapted to mix a compressed air flow with said lubricant, said modular element presenting a mixer element fed with a compressed air flow into which an outlet of a flow regulator fed by the lubricant originating from the pump opens.

Description

technical field [0001] The present invention relates to minimal air / oil lubrication devices. [0002] More specifically, the present invention relates to modular devices. Background technique [0003] Air / oil lubrication represents a recent relevant reality, which is the result of the introduction of advanced technologies that have enabled air / oil lubrication to be used mainly in the field of dry machining. It has also replaced traditional injection systems, which have an adverse impact on the environment. In fact, lubrication is created by supplying a continuous air flow which not only provides means for transport of the oil up to the lubrication point, but also means of cooling for those parts to be lubricated and the lubrication system. [0004] Oil sprayed into the air stream at regular intervals coats the surface to be lubricated, reducing friction and wear. [0005] Currently, there are two types of air / oil lubrication units. [0006] The first type of device inclu...
