Definitions

  • the present invention relates to a compressor comprising an oil suction tube which moves together with the crankshaft.
  • the circulation of the refrigerant liquid used for refrigeration is provided by a compressor.
  • the delivery of the oil to the bearings formed by the movable surfaces is provided by means of an oil suction tube.
  • the oil on the base of the lower casing is sucked and delivered to the bearings to be lubricated and to compressor components to be cooled down.
  • the centrifugal force acting on the oil as a result of the rotation of the crankshaft is used to deliver the oil on the base of the casing to the bearings.
  • the oil first enters through the lower hole of the oil suction tube.
  • the oil moving over the inner surface of the crankshaft reaches the helical channel arranged on the outer surface of the crankshaft.
  • the oil moving through the helical channel is finally discharged from the channel which is arranged on the crankshaft and which opens into the compressor.
  • the oil in the oil suction tube at the idle time of the compressor trickles down to the lower casing with the effect of gravity.
  • the effect of the centrifugal force decreases and sufficient amount of oil for lubrication cannot be provided.
  • a certain period of time elapses for the oil to be sucked from the base of the casing and delivered to the bearings.
  • the aim of the present invention is the realization of a compressor with improved lubrication performance.
  • the compressor realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises an oil suction tube which is attached to the end of the crankshaft; a reservoir which is disposed between the oil suction tube and the crankshaft and which extends along the diameter of the crankshaft in the horizontal axis; and at least one channel with one end opening into the reservoir, which is arranged in the crankshaft.
  • the reservoir disposed between the crankshaft and the oil suction tube By means of the reservoir disposed between the crankshaft and the oil suction tube, an efficient oil suction process is realized.
  • the oil received from the reservoir is directed towards the channel with a smaller diameter than the reservoir which is arranged in the crankshaft, and the flow rate of the oil sucked by the oil suction tube is regulated such that the amount of oil leaving the crankshaft at high speeds is decreased and problems such as lack of oil in the compressor and increase in noise are prevented.
  • the flow rate of the oil is regulated, and the performance at high speeds is improved.
  • the oil suction tube is enabled to stay in the crankshaft with a larger diameter in a stable manner and the oil performance is increased.
  • the compressor comprises two channels which are symmetrical to the central axis of the crankshaft and which open into the reservoir from one end each and outside the crankshaft from the other end.
  • the channel is cylindrical and the channels are inclined from the center of the crankshaft towards the edge thereof.
  • the volume of the crankshaft is divided into two, enabling the oil to be carried more efficiently. Consequently, the effect of capillarity is increased, and the centrifugal force can be used more efficiently, and the oil can be delivered in particular to the components to be cooled or lubricated at low speeds.
  • the oil received from the reservoir is directed towards the channel with a smaller diameter than the reservoir which is arranged in the crankshaft, and the flow rate of the oil sucked by the oil suction tube is regulated such that the amount of oil leaving the crankshaft at high speeds is decreased and an efficient oil suction process is realized while problems such as lack of oil in the compressor and increase in noise are prevented.
  • the compressor (1) comprises a motor (2) composed of two main components, namely a stator (3) and a rotor (4); a crankshaft (5) which transmits the motion received from the motor (2) and which enables the delivery of the oil; a cylinder block (6); a bearing (7) which enables the crankshaft (5) to be borne in the radial direction to the cylinder block (6); an upper casing (8) which covers the movable components; a lower casing (9) at the base of which the oil is disposed; an oil suction tube (10) which is attached to the end of the crankshaft (5); a reservoir (11) which is disposed between the oil suction tube (10) and the crankshaft (5) and which extends along the diameter of the (5) crankshaft in the horizontal axis; and at least one channel (12) with one end opening into the reservoir (11), which is arranged in the crankshaft (5) ( Figure 1 ).
  • the reservoir (11) disposed between the crankshaft (5) and the oil suction tube (10) By means of the reservoir (11) disposed between the crankshaft (5) and the oil suction tube (10), an efficient oil suction process is realized.
  • the oil received from the reservoir (11) is directed towards the channel (12) with a smaller diameter than the reservoir (11) which is arranged in the crankshaft (5), and the flow rate of the oil sucked by the oil suction tube (10) is regulated such that the amount of oil leaving the crankshaft (5) at high speeds is decreased and problems such as lack of oil in the compressor (1) and increase in noise are prevented.
  • the cross-section of the reservoir (11) is quadrilateral.
  • the circulation of the refrigerant fluid used for refrigeration is provided by the compressor (1).
  • the rotational movement of the motor (2) is transmitted to the piston by means of the crank-connecting rod-crankpin mechanism, thus realizing the reciprocating movement of the piston.
  • the refrigerant fluid in the cylinder hole is compressed.
  • the suction leaf on the valve table opens into the cylinder hole, the gas entering the suction valve is compressed and pressurized to the desired level and passes through the exhaust port with the opening of the exhaust leaf on the valve table, thus the high-pressure gas is delivered to the exhaust chamber of the cylinder head and the refrigerant fluid is delivered after the exhaust chamber.
  • the flow rate of the oil is regulated, and the performance at high speeds is improved.
  • the oil suction tube (10) is enabled to stay in the crankshaft (5) with a larger diameter in a stable manner and the oil performance is increased.
  • the compressor (1) comprises two channels (12) which are symmetrical to the central axis of the crankshaft (5) and which open into the reservoir (11) from one end each.
  • one end of the channels (12) opens into the reservoir while the other ends thereof open outside the crankshaft (5) ( Figure 2 ).
  • the channel (12) is cylindrical.
  • the channels (12) are inclined from the center of the crankshaft (5) towards the edge thereof.
  • the crankshaft (5) and the oil suction tube (10) fixed to the end thereof move together.
  • the volume of the crankshaft (5) is divided into two, enabling the oil to be carried more efficiently.
  • the effect of capillarity is increased, and the centrifugal force can be used more efficiently, and the oil can be delivered in particular to the components to be cooled or lubricated at low speeds.
  • the oil received from the reservoir (11) is directed towards the channel (12) with a smaller diameter than the reservoir (11) which is arranged in the crankshaft (5), and the flow rate of the oil sucked by the oil suction tube (10) is regulated such that the amount of oil leaving the crankshaft (5) at high speeds is decreased and an efficient oil suction process is realized while problems such as lack of oil in the compressor (1) and increase in noise are prevented.
