Title:
FLUID COMPRESSION RECYCLING APPARATUS
Document Type and Number:
Japanese Patent JP3153907
Kind Code:
B2
Abstract:
PURPOSE: To attempt adoption of a general automatic control method by reducing an installation cost by a method wherein a low pressure line which recoveres to neighbourhood pressure wherein inlet pressure of a compressor which is divided by a compression ratio is provided, and a suction line of one compressor is switched reciprocally from sucking of a high pressure line to sucking of a low pressure line.
CONSTITUTION: Fluid compressed to injecting pressure into a molding piece in a die 7 with a compressor 3 is reserved in a compression fluid container 5 through a check valve 4, and the compressed fluid is injected into the molding piece in the die 7 by opening an injection valve 6. At a point of time when molding has been completed, a recovery valve 9 is opened and controlled with a compression sensor, a timer, etc., until an inside of a high pressure container 1 reaches equlibrium pressure. When it has reached equilibrium, an inlet valve 12 of a low pressure sucking pressure container 13 is opened, and the compression fluid is recovered until the container 13 reaches the equilibrium pressure. Beside, pressure of the high pressure container 1 is set to a specific pressure with a sensor 21, and low pressure fluid is supplied to the compressor 3 from the low pressure container 13. Then, it is compressed to at least the pressure set with the sensor 21 of the high pressure container 1 and supplied to the high pressure container 1.
