Abstract

A power transfer mechanism for transferring power between rotating components and reciprocating components includes a cam rotatable about an axis and having an odd number of lobes evenly spaced therearound, and a double acting reciprocating member which includes two diametrically opposed pistons, each of which is connected rigidly to a roller follower in operable relationship with the cam, and connecting means disposed between the pistons for resiliently urging the roller followers against the cam.

Claims

1. A power transfer mechanism for transferring power between rotating components and reciprocating components comprising:

a cam rotatable about an axis, said cam having an odd number of lobes evenly spaced therearound;

a double-acting reciprocating member comprising two diametrically opposed pistons, each of said two pistons having roller followers in operable relationship with said cam, and connecting means disposed between two pistons for resiliently urging said roller followers against said cam; and

an access means in a cam case for adjustment of said connecting means.

2. A power transfer mechanism in accordance with claim 1 wherein said connecting means comprise:

(a) a plurality of piston interconnecting rods having parts which fit and slide one within another; and

(b) adjustable resilient means.

3. A power transfer mechanism in accordance with claim 1 wherein said connecting means comprise:

(a) a plurality of piston interconnecting rods having parts which fit and slide one within another;

(b) a coil spring; and

(c) adjustable means.

4. A power transfer mechanism for transferring power between rotating components and reciprocating components comprising:

a cam rotatable about an axis, said cam having an odd number of lobes evenly spaced therearound; and

a double-acting reciprocating member comprising two diametrically opposed pistons, each of said two pistons having roller followers in operable relationship with said cam, and connecting means disposed between said two pistons for resiliently urging said roller followers against said cam.
