Latest Patents

Hiramatsu holds a patent for an improved displacement control valve. This control valve is designed to be incorporated in a variable displacement compressor. The valve includes a valve body and a solenoid for actuating the valve body. The coil of the solenoid is wound about a bobbin made of insulating synthetic resin. A base plate integrally protrudes from the bobbin, and a pair of conducting plates are secured to the base plate. Each plate features a clamping block, and the coil has a pair of terminal wires. Each terminal wire is secured to and electrically connected to one of the clamping blocks. The design includes a holder formed in each plate between the bobbin and the corresponding clamping block. A diode is secured to the holders and is connected in parallel with the coil. The holders prevent tension in the terminal wires from being applied to electrical joints formed between the wires and the clamping blocks, which enhances the valve's reliability.
