Description: |
| Abstract:
My invention relates to explosive-engines, and has for its important improvements therein with a view of securing increased efficiency.
Claim:
The volume capacity of the lubricating chamber is so great that the differential displacement produced by the larger piston results only in a very low compression therein under dimensions shown, and, moreover, any power consumed in effecting the compression within the lubricating-chamber under the compression-stroke of the differential within said lubricating-chamber will be given back to the said piston during its return or expansion stroke.
