Abstract
An engine has a pivotally mounted tie member that connects a piston rod to a second piston rod. Each piston rod is connected to multiple pistons.
Claims14
An engine, comprising:
- a) a first piston and cylinder assembly, said first piston and cylinder assembly comprising at least one cylinder, at least one piston that traverses said at least one cylinder, and a piston rod extending from said at least one piston of said first piston and cylinder assembly;
- b) a second piston and cylinder assembly, said second piston and cylinder assembly comprising at least one cylinder, at least one piston that traverses said at least one cylinder, and a piston rod extending from said at least one piston of said second piston and cylinder assembly;
- and
- c) a tie member that is pivotally mounted to said piston rod of said first piston and cylinder assembly and is pivotally mounted to said piston rod of said second piston and cylinder assembly, and said tie member is pivotally mounted to a case of said engine, wherein said tie member does not rotate more than 180° from a point where said tie member is pivotally mounted to said case of said engine.

An engine, comprising:
- a) a first piston and cylinder assembly, said first piston and cylinder assembly comprising a first piston, a second piston opposed to said first piston, and a piston rod that connects said first piston to said second piston;
- b) a second piston and cylinder assembly, said second piston and cylinder assembly comprising a first piston, a second piston opposed to said first piston, and a piston rod that connects said first piston to said second piston of said second piston and cylinder assembly;
- and
- c) a tie member that is pivotally mounted to said piston rod of said first piston and cylinder assembly and is pivotally mounted to said piston rod of said second piston and cylinder assembly, and is pivotally mounted to a case of said engine, wherein said tie member does not rotate more than 180° from a point where said tie member is pivotally mounted to said case of said engine.
