Latest Patents

Hojyo's latest patents include innovative designs that improve the cooling water passage structure in water-cooled type V-shaped internal combustion engines. One of his patents describes a cooling water passage structure that connects the cooling water passages in cylinders forming a V-shape. This design ensures that the front cooling water passage of a front cylinder communicates effectively with the front cooling water passage of the front cylinder head. Additionally, the rear cooling water passage of a rear cylinder connects with the rear cooling water passage of the rear cylinder head. The design features water pipes and cylindrical portions that project from opposed positions of the front and rear cylinders, extending in a straight line. A rubber connecting pipe is inserted in the water pipes, with ring clips engaged with annular grooves on the outer circumference of the connecting pipe. O-rings are also utilized to ensure a watertight connection between the water pipes.

Another significant patent by Hojyo involves a flow path structure in a water pump. This water pump is designed to feed water under the action of centrifugal force created by the rotation of an impeller within a pump case. The cooling water discharge port is strategically formed at a position offset in the axial direction of the pump from the outer peripheral portion of the impeller. The flow path structure includes a projecting portion that guides cooling water from the outer peripheral portion of the impeller to the discharge port. This design aims to smooth the flow of cooling water, thereby increasing the amount of cooling water discharged and improving the overall pumping performance.
