Latest Patents

One of his latest patents is for a controlled type rotation speed difference sensitive coupling. This invention is designed for use between first and second rotatable members. The coupling consists of a drive housing connected to the first rotatable member, a rotor connected to the second rotatable member, and driving pistons that are operatively carried by the rotor. These pistons have head portions that are slidably engaged with a cam surface wall formed on the inner surface of the drive housing. The rotor features a spool chamber at its center, where a spool is disposed. Balance passages and relief passages extend between working chambers defined by the driving pistons and the spool chamber, with each balance passage having a non-circular orifice that is exposed to the spool chamber and can be closed by the spool.

Another significant patent by Kitamura is for a rotational speed differential responsive type torque transmitting system. This limited slip differential includes a first rotary element, a second rotary element, and a hydraulic unit with multiple reciprocal pistons that engage with an internal cam surface of the first rotary element. The hydraulic unit also features an accumulator and a fluid passage that connects the accumulator to each of the pressure chambers defined by the pistons. A variable flow restrictor is included to automatically regulate the differential slip limiting torque in response to variations in rotational speed between driving wheels.
