Title: Internal combustion engine with free floating auxiliary piston

Abstract

A description is given of an internal combustion engine comprising: a cylinder block defining a power cylinder; a power piston reciprocating within said power cylinder and means defining a combustion chamber with said power cylinder and power piston; an output crank connected to said power piston by a connecting rod; an auxiliary cylinder having a first and a second end; a free floating double acting auxiliary piston disposed within said auxiliary cylinder for reciprocation therein; means defining an intake passage connecting first end of auxiliary cylinder to a source of air; means defining a transfer passage for connecting first end to combustion chamber; means defining an exhaust transfer passage for connecting combustion chamber with second end of auxiliary cylinder; means defining an atmospheric exhaust passage for connecting exhaust transfer passage to atmosphere; a return cylinder coaxially aligned with auxiliary cylinder and opening into auxiliary cylinder; a return piston coaxially aligned with and connected to auxiliary piston, return piston extending from auxiliary piston into return cylinder; a cushioning cylinder opening into said auxiliary cylinder at the second end thereof and being coaxially aligned with said auxiliary cylinder; a cushioning piston connected to and aligned with said auxiliary piston, said cushioning pistonmore » extending toward said second end and entering said cushioning cylinder during reciprocation of said auxiliary piston; a gas transfer passage connecting said return cylinder with said exhaust transfer passage; check valve means within said gas transfer passage for permitting flow only from said exhaust transfer passage to said return cylinder through said gas transfer passage; and valving means disposed within said intake passage, said exhaust transfer passage and said atmospheric exhaust passage for controlling the flow of gases through said passages.« less
