Abstract
Abstract The swash plate engine is provided with an Aspin type rotary valve system with a variable compression capability. The engine may be of four-piston type or six-piston type. The size of the combustion chambers can be changed from time to time to vary the compression ratio. The engine may also be coupled with an accumulator to store the energy of braking for subsequent acceleration of the engine.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
186 words
In combination with an engine having at least one pair of combustion chambers, a reciprocable piston slidably disposed between and in said chambers, and means for reciprocating said piston; said second pair of cylinder chambers, a second reciprocable piston slidably disposed between and in said cylinder chambers and connected to said means for reciprocation thereby; an accumulator having a first chamber for storing a pressure fluid therein, a second chamber for storing a compressible gas therein and a flexible diaphragm separating said first chamber from said second chamber; a conduit connected to said first accumulator chamber with one of said cylinder chambers; a control valve in said conduit for controlling a flow of pressure fluid between said accumulator and said one cylinder chamber; said control valve being operable between a pumping mode in which pressure fluid is pumped from said one cylinder chamber into said first accumulator chamber to brake said engine and a motor mode in which pressure fluid is delivered from said first accumulator chamber to said one cylinder chamber to accelerate said engine; and means for switching said control valve between said positions.
Claim 2
Dependent Claim
186 words
In combination with an engine having at least one pair of combustion chambers, a reciprocable piston slidably disposed between and in said chambers, and means for reciprocating said piston; said second pair of cylinder chambers, a second reciprocable piston slidably disposed between and in said cylinder chambers and connected to said means for reciprocation thereby; an accumulator having a first chamber for storing a pressure fluid therein, a second chamber for storing a compressible gas therein and a flexible diaphragm separating said first chamber from said second chamber; a conduit connected to said first accumulator chamber with one of said cylinder chambers; a control valve in said conduit for controlling a flow of pressure fluid between said accumulator and said one cylinder chamber; said control valve being operable between a pumping mode in which pressure fluid is pumped from said one cylinder chamber into said first accumulator chamber to brake said engine and a motor mode in which pressure fluid is delivered from said first accumulator chamber to said one cylinder chamber to accelerate said engine; and means for switching said control valve between said positions.
Claim 3
Dependent Claim
15 words
The combination as set forth in claim 1 wherein said means is an accelerator pedal.
Claim 4
Dependent Claim
24 words
The combination as set forth in claim 1 wherein said first accumulator chamber stores oil therein and said second accumulator chamber stores nitrogen therein.
