Patent number: 9115606Abstract: A head assembly and valve-less internal combustion engine are disclosed. The head assembly includes a head having a first port extending through the head and a surface defining a portion of a combustion chamber in fluid communication with the first port. The head further includes a first shaft mounted in a first bore of the head between the first port and the combustion chamber. The first shaft includes a first aperture extending therethrough and is rotatable between a first orientation wherein the first shaft blocks fluid communication between the first port and the combustion chamber and a second orientation wherein the first shaft permits fluid communication between the first port and the combustion chamber through the first aperture.Type: GrantFiled: October 9, 2012Date of Patent: August 25, 2015Assignee: VAZTEC, LLCInventors: Darrick Vaseleniuck, David Vaseleniuck
