Abstract

Motor sa slobodnim klipovima, s, naznačen time, dva klipa (3,4) koji su medusobno čvrsto spojeni s jednom ili više klipnjača, koje osciliraju unutar jednog cilindra (2); jednim cilindrom (2) koji je na svojim suprotnim krajevima opremljen glavama cilindra (7), u kojim se klipovi (3,4) obostrano zagrijavaju, jednom pregradom (5) koja odvaja cilindar (2), kroz koju se aksijalno provode klipnjače (6); jednim radnim medijem koji se nalazi na poleđini klipova (3,4), koji gibanjem klipova (3,4) prekopovratnih ventila (8,9) pogoni agregat (12). Patent sadrži još 2 patentna zahtjeva.Free piston engine, s, characterized in that two pistons (3,4) are tightly coupled to one or more piston rods, which oscillate within a single cylinder (2); a single cylinder (2) fitted at its opposite ends with cylinder heads (7), in which the pistons (3,4) are heated on both sides, one barrier (5) separating the cylinder (2) through which the connecting rods (6) are axially extending ); one working medium located on the back of the pistons (3,4), which drives the aggregate (12) by moving the pistons (3,4) through the check valves (8,9). The patent contains 2 more patent claims.
