| 20100278678 | SCREW COMPRESSOR - A screw compressor includes a casing having a cylinder, a cylindrical-shaped screw rotor disposed in the cylinder, a gate rotor and a seal portion. The screw rotor has a plurality of spiral-shaped groove portions formed in an outer peripheral surface. The gate rotor has a plurality of tooth portions engaged with the groove portions of the screw rotor to define compression chambers on one side of the gate rotor. The tooth portions are formed at an outer peripheral surface of the gate rotor. The seal portion is disposed on a side of the gate rotor opposite to the one side where the compression chambers are defined. The seal portion is arranged to block a space between a neighboring pair of the tooth portions of the gate rotor. | 11-04-2010 |
| 20100284848 | SCREW COMPRESSOR - A screw compressor includes a screw rotor having a plurality of helical grooves, a casing containing the screw rotor and a gate rotor. The casing includes a discharge port on an inner peripheral surface of the casing. The gate rotor has gates meshing with the helical grooves of the screw rotor to compress gas in compression chambers to discharge the gas from the discharge port after being compressed. The compression chambers are defined by the helical grooves, the casing, and the gates. The discharge port is divided into a first port and a second port when two adjacent helical grooves of the plurality of helical grooves is open to the discharge port as a result of rotation of the screw rotor, with one of the two adjacent helical grooves being open in the first port and the other of the two adjacent helical grooves being open in the second port. | 11-11-2010 |
| 20100329918 | SCREW COMPRESSOR - A screw compressor includes a screw rotor, a gate rotor and an injection mechanism. The screw rotor is provided with multiple helical grooves. The gate rotor is provided with multiple gates meshing with the helical grooves to form at least one compression chamber between at least one of the helical grooves and at least one of the gates. The compression chamber is configured and arranged such that refrigerant taken-in from a starting-end side of the helical groove is compressed and discharged from a dead-end side of the helical groove. The injection mechanism is configured and arranged to inject oil or refrigerant from a discharge hole of the injection mechanism into the compression chamber such that rotational torque is imparted in a direction in which the screw rotor is rotated at a time of compression. | 12-30-2010 |

| 20090255489 | Straddle Type Vehicle - A motorcycle includes an engine, a radiator that cools a cooling liquid, a first piping that connects the engine to the radiator, and a second piping that connects the engine to the radiator. The second piping, engine, radiator and first piping form a circulating circuit through which cooling liquid circulates. At least one of the first and second pipings is substantially constituted by resin piping. The time required to warm up the engine is thereby reduced. | 10-15-2009 |
| 20090255748 | Motorcycle - A motorcycle including a radiator and having an engine offset, and in which increase in vehicle width is suppressed. A center of the engine is out of alignment with respect to a center of a head pipe toward one side in the vehicle width direction. The radiator is arranged in front of the engine. Cooling liquid flows in the radiator in the vehicle width direction. A first piping extends rearward from the other end portion of the radiator and a rear end portion of the first piping is connected to the engine. A second piping connects one end portion of the radiator in the vehicle width direction to the engine. The second piping extends from the one end portion of the radiator to the other side of the engine in the vehicle width direction, between the radiator and the engine, and extends rearward of the other side of the engine in the vehicle width direction. | 10-15-2009 |
| 20090260595 | Engine and Straddle-Type Vehicle Including the Engine - An engine that is lighter in weight includes a crankcase, a crankshaft, a body cylinder, a head cylinder, a piston, a piston ring and a cylinder fixing bolt. The piston ring is arranged on an outer peripheral surface of the piston. One end portion of the cylinder fixing bolt extends toward the head cylinder and an other end portion of the cylinder fixing bolt extends toward the crankcase. The cylinder fixing bolt connects the head cylinder, the body cylinder and the crankcase to one another. A lower section of the body cylinder is located within the crankcase. The piston ring abuts on the lower section when the piston is located at a bottom dead center. | 10-22-2009 |
