Spiral type Compressor with variable displacement mechanism

摘要

The present Invention relates to a Spiral type Compressor includes a Housing that has an Inlet and an outlet Orifice.A Spiral fixed ready at within the Housing and has a circular End plate which extends a first element Spiral towards the Interior of the accommodationA Spiral orbiting End plate has a circular element which extends a Second SpiralFirst and second Elements interajustan Spirals in an angular and radial deviation to a Plurality of contacts in line to define at least a couple of Fluid bags persoOr the inside of the Housing, a Drive Connected functionally to the orbiting Spiral for the orbital motion of the orbiting Spiral,An anti rotation mechanism for Preventing rotation of the orbiting Spiral during the orbital Motion to change the volume of Fluid in the Bag,Circular End plate of the fixed Spiral that divides the Interior of the accommodation in a Front Chamber and a rear Chamber, front camera, Associated with the input Port,Divided into the posterior Chamber and a discharge Chamber that communicates with the output hole and a Central Fluid Bag formed by both Spiral and a pressure Chamber, IntermediateAt least a couple of Holes formed through the End plate of the fixed circular Spiral to form a channel for Fluid between the bags and the intermediate pressure Fluid Chamber.A Communication Channel is formed through the spiral fixed circular plate to form a channel for Fluid between the pressure Chamber and the Middle Chamber FrontAnd a control Element disposed on a portion of the intermediate pressure Chamber to control the communication between the intermediate pressure Chamber and the Suction Chamber.The Improvement includes control Elements comprising a Cylinder, a piston arranged inside the Cylinder and a Sliding element of Communication,Cylinder which is connected with the intermediate pressure Chamber, Suction Chamber and discharge Chamber.The Piston that slides inside the Cylinder according to the pressure difference between the pressure in the Cylinder and the pressure in the pressure Chamber, IntermediateAnd the communication element that let out the gas discharged from the Cylinder to the Suction Chamber when the piston is pushed Upward from a Lower position.
