Abstract
An apparatus for mutual conversion between circular motion and reciprocal motion includes a lever member which is rotatably mounted on a line connecting a rotational center and a circumference of a rotary disk, the lever member having a fulcrum, an action point and a force point, and being provided with a first regulator serving as an action point regulator land a second regulator serving as a movable fulcrum regulator. The first regulator is coupled to a reciprocating body. The movable fulcrum regulator has support members for supporting the fulcrum point and the first regulator has support members for supporting the action point in a longitudinal direction of the lever member.
Claims5
A radial engine including a plurality of basic engine units radially arranged around an output axle, each of the units being provided for mutual conversion between circular motion and reciprocal motion, each of said basic engine units comprising:
- a rotary body connected to the output axle;
- a reciprocating motor including a cylinder having first and second end portions each of which a fuel gas inlet and outlet, and an ignition unit and a piston body having two piston members inserted in the cylinder to face the first and second end portions;
- and
- a lever member, having a fulcrum as well as a force point, and an action point which is rotatably mounted at a point on a line connecting a rotational center and a circumference of the rotary body, the force point being provided with a first regulator and the fulcrum being provided with a second regulator for operating the fulcrum as a movable fulcrum;
- wherein the force point provided with the first regulator is coupled to said piston body of the reciprocating motor, the piston body is movably mounted in said cylinder, and the first and second regulators have support members for supporting the force point and the fulcrum to be movable in a longitudinal direction of the lever member.
A two-cylinder radial engine comprising first and second basic engine units radially arranged around an output axle, each of the first and second basic engine units being provided for mutual conversion between circular motion and reciprocal motion, each of the first and second basic engine units comprising:
- a rotary body connected to the output axle;
- a reciprocating motor including a cylinder having first and second end portions each of which has a fuel gas inlet and outlet, and an ignition unit, and a piston body having first and second piston members provided in the cylinder to face the first and second end portions;
- and
- a lever member, having a fulcrum as well as a force point and an action point, which is rotatably mounted at a point on a line connecting a rotational center and a circumference of the rotary body, the force point being provided with a first regulator and the fulcrum being provided with a second regulator for operating the fulcrum as a movable fulcrum;
- wherein the force point provided with the first regulator is coupled to said piston body of the reciprocating motor, the piston body is movably mounted in said cylinder, and the first and second regulators have support members for supporting the force point and the fulcrum to be movable in a longitudinal direction of the lever member.
A four-cylinder radial engine comprising first, second, third and fourth basic engine units radially arranged around an output axle, each of the first, second, third and fourth basic engine units being provided for mutual conversion between circular motion and reciprocal motion, each of the first, second, third and fourth basic engine units comprising:
- a rotary body connected to the output axle;
- a reciprocating motor including a cylinder having first and second end portions each of which has a fuel gas inlet and outlet, and an ignition unit, and a piston body having first and second piston members provided in the cylinder to face the first and second end portions;
- and
- a lever member, having a fulcrum as well as a force point and an action point, which is rotatably mounted at a point on a line connecting a rotational center and a circumference of the rotary body, the force point being provided with a first regulator and the fulcrum being provided with a second regulator for operating the fulcrum as a movable fulcrum;
- wherein the force point provided with the first regulator is coupled to said piston body of the reciprocating motor, the piston body is movably mounted in said cylinder, and the first and second regulators have support members for supporting the force point and the fulcrum to be movable in a longitudinal direction of the lever member.
