Oiler system and device

Claim 2

A continuous flow oiler system including, in combination, inlet means for coupling to a supply of compressed, gaseous, power media; outlet means for coupling to a work tool to be powered by said media; control valve means having an inlet coupled to said inlet means and also an outlet; mixing chamber means intercoupled between said outlet of said control valve means and said outlet means; variable-volume lubricant chamber means having an inlet port and an outlet port; piston means independent of said control valve for progressively reducing the volume of said chamber means when said valve means is open; means coupled to said outlet of said control valve means and responsive to media pressure thereat for advancing said piston means to so reduce the volume of said chamber means; means for returning said piston means when said valve means is closed to expand the volume of said chamber means; first means for coupling said inlet port to a source of lubricating fluid; an injection nozzle communicating with said mixing chamber, and second means for coupling said outlet port to said injection nozzle.

Claim 3

Claim 4

A continuous flow oiler device including, in combination, an outer cylindrical housing having one end constructed for coupling to a valved gaseous pressure source and a second end constructed for coupling to gaseous-pressured operated work tool; a lubricant injection nozzle disposed in said outer cylindrical housing and facing downstream; structure disposed within said outer cylindrical housing and defining a variable-volume lubricant chamber; piston mean disposed within said outer cylindrical housing, facing upstream, and in part defining said lubricant chamber to vary the volume thereof; one-way inflow inlet means affixed to said outer cylindrical housing and to said structure and communicating with the interior thereof, for fixedly spacing said structure coaxially within said outer cylindrical housing in spaced relationship with respect thereto and also for introducing fluid lubricant within said structure, the spacing between said structure and said outer cylindrical housing defining an annular gaseous-flow passageway extending throughout the length of said outer cylindrical housing one-way outflow outlet means connected to said structure, communicating with the interior thereof, and connected to said nozzle; and return spring means for returning said piston means upstream in the absence of gaseous pressure applied thereto.

Claim 5

A continuous flow oiler device including, in combination, an outer cylindrical housing having one end constructed for coupling to a valved gaseous pressure source and a second end constructed for coupling to gaseous-pressured operated work tool; a lubricant injection nozzle disposed in said outer cylindrical housing and facing downstream; structure disposed within said outer cylindrical housing and defining a variable-volume lubricant chamber; piston mean disposed within said outer cylindrical housing, facing upstream, and in part defining said lubricant chamber to vary the volume thereof; one-way inflow inlet means affixed to said outer cylindrical housing and to said structure and communicating with the interior thereof, for fixedly spacing said structure coaxially within said outer cylindrical housing in spaced relationship with respect thereto and also for introducing fluid lubricant within said structure, the spacing between said structure and said outer cylindrical housing defining an annular gaseous-flow passageway extending throughout the length of said outer cylindrical housing one-way outflow outlet means connected to said structure, communicating with the interior thereof, and connected to said nozzle; and return spring means for returning said piston means upstream in the absence of gaseous pressure applied thereto.

Claim 6

A continuous flow oiler device including, in combination, an outer cylindrical housing having one end constructed for threaded coupling to a gaseous pressure operated work tool; a lubricant injection nozzle disposed in said outer cylindrical housing facing downstream, a cylinder disposed within and mounted in annularly spaced relationship with respect to said outEr cylindrical housing throughout the length thereof; structure disposed in said outer cylindrical housing and defining a variable-volume lubricant chamber; piston means operably disposed in said cylinder and having a hollow piston rod extension passing into and communicating with the interior of said structure, said piston means in part defining said lubricant chamber to vary the volume thereof; one-way inflow inlet means connected to said structure ad communicating with the interior thereof, said inlet means being constructed for connection to an external lubricant reservoir; one-way outflow outlet means connected to said structure, communicating with the interior thereof, and connected to said nozzle; and return spring means disposed within said structure and engaging said piston means interior of said piston rod.

Claim 7

A continuous flow oiler device including, in combination, an outer cylindrical housing having one end constructed for threaded coupling to a gaseous pressure operated work tool; a lubricant injection nozzle disposed in said outer cylindrical housing facing downstream, a cylinder disposed within and mounted in annularly spaced relationship with respect to said outEr cylindrical housing throughout the length thereof; structure disposed in said outer cylindrical housing and defining a variable-volume lubricant chamber; piston means operably disposed in said cylinder and having a hollow piston rod extension passing into and communicating with the interior of said structure, said piston means in part defining said lubricant chamber to vary the volume thereof; one-way inflow inlet means connected to said structure ad communicating with the interior thereof, said inlet means being constructed for connection to an external lubricant reservoir; one-way outflow outlet means connected to said structure, communicating with the interior thereof, and connected to said nozzle; and return spring means disposed within said structure and engaging said piston means interior of said piston rod.

Claim 8

Structure according to claim 4 wherein said device includes venting means fixedly connected to said outer cylindrical housing and mountingly engaging said cylinder to mount the same in place and to communicate with the interior thereof forwardly of said piston means.
