Abstract
A radial motor or pump has a stator (10) inside which a rotor (15) rotates. The stator caries one or more radial cylinders (L, M and N) in each of which a piston (20) is slidable. The end of each cylinder (L, M or N) or a ring (43) slidable therein bears against and is a sealing rubbing fit with the internal surface (12) of the stator (10). The pistons (20) are connected as by connecting rods (21) to a crank pin (22) of a crankshaft (24). Gears interconnect the stator, rotor and crankshaft to cause the rotor (15) and crankshaft (24) to rotate at the same speed but in opposite directions.
Claims17
A radial rotary fluid pressure machine including a stator, a first surface formed on the stator as a surface of revolution about a first axis, a rotor, a second surface formed on part of the rotor as a surface of revolution about the first axis, the first and second surfaces being mounted for relative sliding rotation therebetween, characterised by a working cylinder formed in the rotor substantially radial to the first axis, a piston slidable axially in the cylinder and being a sliding fit therein, a drive shaft, coupling means interconnecting the piston and the drive shaft, the coupling means causing reciprocation of the piston in the cylinder to rotate the drive shaft or rotation of the drive shaft to cause reciprocation of the piston in the cylinder, a port formed in the stator through said first surface, at a predetermined circumferential location in the stator, through which port fluid may pass to or from the cylinder, and drive means interconnecting the rotor and the drive shaft, the drive means being arranged to rotate the rotor and the drive shaft relative to the stator at predetermined speeds and directions of rotation.
An internal combustion engine as claimed in any preceding claim characterised in that it includes a first and second of said ports spaced circumferentially around the stator, one port being adapted to admit air or air/fuel mixture to the cylinder and the other port being an exhaust port from the cylinder.
A radial rotary internal combustion engine including a stator a first surface formed on the stator a surface of revolution about a first axis, a rotor, a second surface formed on part of the rotor as a surface of revolution about the first axis, the first and second surfaces being mounted for relative sliding rotation therebetween characterised by a plurality of working cylinders formed in or on the rotor substantially radial to the first axis and spaced evenly circumferentially, a piston slidable axially in each cylinder and being a sliding fit therein, a drive shaft formed with a crank throw and a crank pin thereon, connecting rods connecting each piston to the same crank pin or each to a separate one of a plurality of coaxial crank pins, for each cylinder there being a port formed in the stator through said first surface, at a predetermined circumferential location in the stator, through which port fluid may pass to or from the cylinder, each said port being exposed to one only of said cylinders during rotation thereof, and drive means interconnecting the rotor and the drive shaft, the drive means being arranged to rotate the rotor and the drive shaft relative to the stator at predetermined speeds and directions of rotation.
A radial rotary internal combustion engine substantially as described herein and as shown in the accompanying drawings.
