Latest Patents
One of Koeda's latest patents is for a centrifugal compressor. This design includes a rotary shaft, a compression mechanism that compresses fluid, a motor, an inverter, a housing, and a wiring unit. The compression mechanism features an impeller, a suction chamber, a diffuser, and a volute. The housing is composed of several members, including a motor housing member, an impeller housing member, a suction housing member, and an inverter housing member. Notably, the housing has a through hole that extends to the inside of the inverter housing member from the motor housing member, with the wiring unit disposed in the housing and inserted in the through hole. This innovative design ensures that the through hole is positioned away from the volute, while a suction passage is located away from the through hole in the circumferential direction of the rotary shaft.
Another significant patent by Koeda is for a variable displacement compressor with a drain passage. This compressor includes a swash plate, a housing, and a displacement control valve. The housing contains a crank chamber where the swash plate is located, along with a discharge chamber and a suction chamber. The housing is formed by separate members fastened together with plural bolts inserted through bolt holes. The displacement control valve features a first valve member that connects the crank chamber and the discharge chamber, allowing for control over the compressor's displacement. Additionally, the valve chamber is connected to the crank chamber by a drain passage, which is strategically designed to serve as the bolt hole located at the lowest point when the compressor is installed.
