Improvements to a pneumatic motor

A pneumatic motor for rotating an axle comprising:

• a. a housing comprising:
• b. an air intake port;
• c. an air exhaust port;
• d. at least two cylinders;
• each cylinder being positioned radially from the axle;
• e. at least two air channels in communication with each cylinder;
• f. at least two pistons, each piston attached to the axle by a connecting rod, each piston and respective connecting rod being radially aligned, in respect of the axle and in a distinct radial plane from each other in a staggered vertical arrangement, each piston to be received in one of said at least two cylinders;
• each connecting rod being attached centrally offset in relation to a central axis of said axle;
• and
• g. a modular bushing fit onto said axle to regulate communication of said air intake port and said air exhaust port with said at least two air channels in communication with each cylinder;
• wherein during a power stroke of one piston, said axle allows said air intake port to be in communication with the air channel in communication with one cylinder allowing air from the air intake port to enter into the cylinder;
• and during an exhaust stroke of one piston, said axle allows said air exhaust port to be in communication with the air channel in communication with said one cylinder allowing air to exit the cylinder through the air exhaust port;
• wherein, when one connecting rod and piston are in power stroke, the other connecting rod and piston are in exhaust stroke.

A pneumatic motor for rotating an axle comprising:

• a. A housing comprising an air intake port;
• b. an air exhaust port;
• c. at least three cylinders;
• each cylinder being positioned radially from the axle;
• each cylinder being in a distinct radial plane from each other;
• d. at least two air channels in communication with each cylinder;
• e. at least three pistons, each piston attached to the axle by a connecting rod, each piston and respective connecting rod being radially aligned, in respect of the axle and in a distinct radial plane from each other, each piston to be received in one of said at least three cylinders;
• each connecting rod being attached centrally offset in relation to a central axis of said axle;
• and
• f. a modular bushing fit onto said axle to regulate communication of said air intake port and said air exhaust port with said at least two air channels in communication with each cylinder;
• wherein during a power stroke of one piston, said axle allows said air intake port to be in communication with the air channel in communication with one cylinder allowing air from the air intake port to enter into the cylinder;
• and during an exhaust stroke of one piston, said axle allows said air exhaust port to be in communication with the air channel in communication with said one cylinder allowing air to exit the cylinder through the air exhaust port;
• wherein when one connecting rod and piston are in power stroke, the other connecting rod and piston are in exhaust stroke and a third connecting rod and piston are in between an exhaust stroke and a power stroke.

A pneumatic motor for rotating an axle comprising:

• a. a housing comprising an air intake port;
• b. an air exhaust port;
• c. at least six cylinders;
• each cylinder being positioned radially from the axle;
• each cylinder being in a distinct radial plane from each other;
• d. at least two air channels in communication with each cylinder;
• e. at least six pistons, each piston attached to the axle by a connecting rod, each piston and respective connecting rod being radially aligned, in respect of the axle and in a distinct radial plane from each other, each piston to be received in one of said at least six cylinders;
• each connecting rod being attached centrally offset in relation to a central axis of said axle;
• f. a modular bushing fit onto said axle to regulate communication of said air intake port and said air exhaust port with said at least two air channels in communication with each cylinder;
• g. wherein during a power stroke of a piston, said axle allows said air intake port to be in communication with the air channel in communication with a cylinder of the piston during a power stroke allowing air from the air intake port to enter into the cylinder;
• and during an exhaust stroke of a piston, said axle allows said air exhaust port to be in communication with the air channel in communication with a cylinder of the piston undergoing an exhaust stroke allowing air to exit the cylinder through the air exhaust port.
