Electric valve control device and electric valve device including the same

. . To provide an electric valve control device capable of preventing a delay at the time of starting a control of an electric valve by shortening a standby time of an air conditioner or the like when power is input again or a sleep mode is cancelled and an electric valve device including the same. After receiving a power-off signal predicting a power-off operation of an electric valve 9 or a sleep transition signal predicting a sleep mode transition operation thereof from an outside, (current) valve opening degree information at the time of stopping an operation of the electric valve 9 is stored in an eeprom (a nonvolatile storage unit) 11c. ...

Variable -capacity compressor control valve

. . . . . . . . . . Provided is a variable-capacity compressor control valve where the size of a plunger can be reduced, the machining and assembly process can be simplified, weight reduction can be achieved, and cost reduction can also be achieved, for example. The plunger has a slit through which a valve element is assembled to the plunger by being inserted from a lateral side. ... Fujikoki Corporation

Variable-capacity compressor control valve

Provided is a variable-capacity compressor control valve where a decrease in the sealability or the operability due to shaft misalignment can be effectively suppressed without requiring high dimensional accuracy. The dimensions and the shape of each part are designed such that when the sub valve element closes the in-valve release passage, the tapered portion (sub valve element portion) provided at the lower end portion of the sub valve element enters the release through-hole of the in-valve release passage, and the sub valve element is thus aligned with the main valve element by the tapered portion.. ...

Variable-capacity compressor control valve

Provided is a variable-capacity compressor control valve where a valve body can be easily machined and the machining time and machining cost can be reduced without a decrease in the valve closing property or a decrease in the slidability of the valve element due to shaft misalignment. The valve body includes a support member having formed therein a valve orifice and a guide hole into which the valve element is adapted to be slidably fitted and inserted; and a body member having formed therein a ps inlet/outlet port, a pd introduction port, and a pc inlet/outlet port. ...

Variable-capacity compressor control valve

Provided is a variable-capacity compressor control valve that can suppress a decrease in the efficiency by reducing the amount of leakage in the valve without requiring severe accuracy of the components, avoid possible operation failures, and suppress the influence on the sliding resistance as well as the influence on the control characteristics. A main valve element of a valve element or a valve body is provided with a flexible or elastic sealing member. ... Fujikoki Corporation

Accumulator

Provided is an accumulator capable of effectively suppressing a bumping phenomenon and the following impact noise during the starting of a compressor without making the structure of the accumulator complicated or increasing the cost and the size thereof, and so having cost-effectiveness. An accumulator includes: a tank 10 having an inflow port 15 and an outflow port 16; and a double-pipe structured outflow pipe 30 including an inner pipe 31 joined to the outflow port 16 and hanging inside of the tank 10, and an outer pipe 32 disposed outside of the inner pipe 31. ... Fujikoki Corporation

Accumulator

Provided is an accumulator capable of effectively suppressing a bumping phenomenon and the following impact noise without making the structure of the accumulator complicated or increasing the cost and the size thereof. A protrusion serving as an origination of boiling is disposed at a part soaked with a liquid part including liquid-phase refrigerant and oil accumulated in the tank 10 of the accumulator 1. ... Fujikoki Corporation

Valve controller, valve controlling method, refrigeration and cold storage system, device and method for controlling the system

To provide a motor-driven valve with a small number of parts, with excellent assemblage, capable of maintaining a large valve port diameter even downsized, and to prevent deterioration of housing environment due to sound caused by the impact and shortened life that are generated by collisions of closing limit stopper parts. A motor-driven valve according to the present invention comprises: a male screw member rotating in accordance with a rotation of a rotor of an electric motor and engaging with a female screw member fixed to a valve main body; a valve body contacting to and separating from a valve seat in the valve main body by a rotation of the male screw member; two stopper parts rotating in accordance with the rotation of the rotor of the electric motor; an opening limit stopper part mounted to the female screw member, the opening limit stopper part contacting with one of the two stopper parts in a fully-opened state of the motor-driven valve to restrict the rotation of the male screw member in a direction that the motor-driven valve opens; and a closing limit stopper part mounted to the female screw member, the closing limit stopper part contacting with another stopper part in a fully-closed state of the motor-driven valve to restrict the rotation of the male screw member in a direction that the motor-driven valve closes.. ...
