Definitions

  • the present invention relates to a compressor whereof the first start-up lubrication is improved.
  • the circulation of the refrigerant used for refrigeration is provided by a compressor.
  • the delivery of the lubricating oil to the bearings formed by the movable surfaces is provided by means of an oil suction duct.
  • the aim of the present invention is the realization of a compressor whereof the lubrication is improved.
  • the compressor realized in order to attain the aim of the present invention comprises a pump with an inlet, opening to near the oil suction duct orifice and the propeller means inside thereof is driven by a drive mechanism.
  • the pump is of the radial or reciprocating type.
  • the drive means comprises a cable that delivers electricity from the electric inlet of the compressor to the pump motor and hence provides actuation of the pump.
  • the compressor comprises a control card.
  • the pump is actuated at the chosen times by means of the control card.
  • the drive means comprises at least two magnets. At least one of the magnets is disposed on the rotor and the other on the shaft that delivers the motion of the drive mechanism to the propeller means. The attraction-repulsion force generated between the magnets actuates the pump.
  • the magnet is positioned on the motor, preferably embedded in the end rings disposed on the rotor base.
  • the drive means comprises a disc.
  • the disc is disposed on the shaft and the side is in contact with the rotor. The disc transfers the rotation of the rotor to the pump and thus the pump is actuated.
  • the pump is secured on at least one of the legs whereon the motor is emplaced or on the stator by means of a retaining member.
  • Figure 1 - is the schematic view of the compressor of the present invention.
  • Figure 2 - is the schematic front partial view of detail C in Figure 1 in an embodiment of the present invention.

  • Figure 11 - is the schematic front partial view of yet another embodiment of the present invention.
  • the elements illustrated in the figures are numbered as follows:
  • the compressor (1) comprises a motor (2) consisting of two main components, a stator (3) and a rotor (4), a crankshaft (5) that delivers the motion received from the motor (2), a cylinder block (7) , a bearing (8) that maintains the crankshaft (5) to be beared on the cylinder block (7) in the radial direction and an oil suction duct (6) secured to the end of the crankshaft (5) for delivering the sucked lubricant oil to the bearing (8).
  • a motor (2) consisting of two main components, a stator (3) and a rotor (4), a crankshaft (5) that delivers the motion received from the motor (2), a cylinder block (7) , a bearing (8) that maintains the crankshaft (5) to be beared on the cylinder block (7) in the radial direction and an oil suction duct (6) secured to the end of the crankshaft (5) for delivering the sucked lubricant oil to the bearing (8).
  • the compressor (1) furthermore comprises
  • a pump (9) having a body (10), an inlet (11) opening to the reservoir collecting the oil (Y), an outlet (12) that opens to a point close to the oil suction duct (6) orifice and a propelling means (13) for pumping out the oil received in from the inlet (11) through the outlet (12) and
  • the propeller means (13) is activated by the drive received from the drive mechanism (14) maintaining the oil to be sucked from the inlet (11) and to be sprayed from the outlet (12) to inside the oil suction duct (6) ( Figure 2 and Figure 3). Accordingly, lubrication is accomplished effectively and rapidly.
  • the pump (9) is of the radial type.
  • the propeller means (13) is a radial wheel. The propeller means (13) rotates by the drive received from the drive mechanism (14) and maintains the oil to be received into the pump (9) through the inlet (11) and to be pumped toward the oil suction duct (6) from the outlet.
  • the pump (9) is of the reciprocating type.
  • the propeller means (13) is a piston.
  • the propeller means (13) reciprocates by the drive received from the drive mechanism (14) and maintains the oil to be received into the pump (9) through the inlet (11) and to be pumped toward the oil suction duct (6) from the outlet (12).
  • the pump (9) comprises an electric pump motor (17) and the drive mechanism (14) comprises a cable (16) that connects the pump motor (17) to the electric inlet of the compressor (1).
  • the pump (9) is driven by the electric delivered via the cable (16) ( Figure 1).
  • the compressor (1) furthermore comprises a control card (15) that is used in actuating the pump (9). Accordingly, the pump (9) can only be actuated at the chosen times, for example when the speed of the motor (2) and hence the oil suction performance is low.
  • the pump (9) comprises a shaft (24) that transfers the motion of the drive mechanism (14) to the propeller means (13).
  • the drive mechanism (14) comprises at least two magnets (19), one emplaced on the rotor (4) base and the other on the shaft (24). The magnets (19) are so disposed that the attraction-repulsion force therebetween results in actuating the pump (9) ( Figure 4 and Figure 5).
  • the compressor (1) comprises an end ring (18) on the rotor (4) base and the magnets (19) disposed on the motor (2) are embedded in the said end ring (18).
  • the pump (9) comprises a shaft (24) that delivers the motion of the drive mechanism (14) to the propeller means (13).
  • the compressor (1) furthermore comprises a disc (20) mounted on the shaft (24). The side of the disc (20) contacts the rotor (4). The disc (20) delivers the friction force generated thereon by the rotation of the rotor (4) to the shaft (24) and hence to the propeller means (13) thereby providing the actuation of the pump (9).
  • the compressor (1) furthermore comprises legs (22) whereon the motor (2) is emplaced.
  • the pump (9) is secured on one of the legs (22) ( Figure 8).
  • the leg (22) comprises at least one extension (23) that extends toward the oil suction duct (6), whereon the pump (9) is secured. Consequently, the pump (9) can be easily positioned opposite the oil suction duct (6).
  • the pump (9) is secured from both sides on both of the legs (22) ( Figure 9). Accordingly, the pump (9) can be supported in a balanced manner.
  • the compressor (1) comprises a retaining member (21) for securing the pump (9) to the stator (3) ( Figure 10).
  • the retaining member (21) is configured like a Z, preferably with one leg fastened to the pump (9) and the other leg on the stator (3).
