Latest Patents

Takada's latest patents include a hydraulic control valve and a valve-timing control device for internal combustion engines. The hydraulic control valve allows for increased flexibility in port layout without requiring high dimensional accuracy. It features a cylindrical valve body with retard and advance ports, along with reintroduction ports. A spool valve is provided, which moves axially within the valve body, enabling the switching between the supply and discharge of working fluid to and from the hydraulic chambers. Additionally, the control valve includes a cylindrical sleeve made of synthetic resin, which is fixed to the outer surface of the valve body, and an actuator that facilitates the movement of the spool valve.

The valve-timing control device is designed to minimize the axial length of the device, thereby improving its mountability. This valve incorporates a valve body that acts as a cam bolt, connecting a vane rotor to one end of a camshaft. It also features a sleeve fixed to the valve body and a spool valve element that is axially slidably housed within the sleeve. This design allows for efficient switching between the supply and discharge of working fluid to the phase-retard and phase-advance working chambers.
