Definitions

• the present invention relates to a compressor comprising a protection member.
• the sliding bearings wherein the crankshaft operates and the other movable members are lubricated with the oil disposed in the compressor casing.
• lubrication provides friction losses of the movable members to be decreased, abrasion to be prevented and the temperature of the compressor members to be decreased.
• oil disposed at the bottom of the casing may enter into the cooling system pipes that open into the casing and is pumped into the cooling system at the first operation after the transportation. This situation decreases the cooling efficiency and damages the members of the cooling system. For this reason, cooling device, wherein compressors are used, are transported with great care and positioned so that the compressor remains parallel to the floor.
• the pipe on the suction muffler is extended towards into the inlet pipe of the casing; however, in these embodiments, oil cannot be fully prevented from entering into the system, and also amount of noise generated increases.
• a compressor comprising a suction muffler.
• the inlet of the suction muffler extends into the inlet pipe.
• the area through which the oil may enter the suction muffler is narrowed.
• the aim of the present invention is the realization of a compressor wherein oil is prevented from entering into the cooling system pipes that open into the casing during the transportation.
• 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 inlet pipe that is disposed on the casing and that provides the refrigerant coming from the evaporator to be received into the casing, and a passage pipe that delivers the air coming from the inlet pipe to the compression system.
• the protection member is disposed on at least one of the inlet pipe and the passage pipe. When the compressor is brought to an inclined position, the protection member closes the mouth of the inlet pipe and/or the passage pipe, thus preventing the oil from entering therein.
• the protection member comprises a shaft that extends longitudinally the diameter line, preferably parallel to the floor, of the cross-section of the inlet pipe and/or the passage pipe, a circular lid that is disposed on the part of the shaft remaining in the inlet pipe and/or the passage pipe, with a diameter almost equal to the pipe wherein it is located and a block that is disposed at the end of the shaft remaining outside the pipe and that moves the shaft so that the lid closes the inlet pipe and/or the passage pipe as the compressor moves.
• the movement of the block is limited between two stoppers.
• One of the stoppers stops the block in a first position wherein the lid almost entirely closes the inlet pipe and/or the passage pipe, and the other stops the block in a second position wherein the lid is perpendicular to the cross-section of the inlet pipe and/or the passage pipe. While the block moves between the two stoppers, the lid moves between the first position and the second position.
• the passage pipe is disposed on a suction muffler that provides the noise generated due to the movement of the the refrigerant to be attenuated.
• the refrigerant leaving the inlet pipe passes to the passage pipe that is across from the part of the inlet pipe in the casing and the refrigerant is delivered to the cylinder after entering into the suction muffler.
• the present invention it becomes possible to tilt or lay down the compressor and the cooling device wherein the compressor is used, thereby decreasing the transportation and storage costs. Ease of utilization is obtained, since no user intervention is needed for the protection member to prevent the oil from entering the inlet pipe and/or the passage pipe. As the user starts tilting the cooling device and hence the compressor, the protection member is activated and starts closing the inlet pipe and/or the passage pipe.
• Figure 1 – is the schematic view of a compressor.
• Figure 2 – is the partial view of a compressor.
• Figure 3 – is the perspective view of the suction muffler when the protection member is mounted on the passage pipe.
• Figure 4 – is the view of detail A in Figure 3.
• Figure 5 — is the perspective view of the suction muffler when the protection member is mounted on the passage pipe.
• Figure 6 — is the view of detail B in Figure 5.
• the compressor (1) comprises a casing (2) carrying the components therein and wherein the oil lubricating the movable members is placed, an inlet pipe (3) that is disposed on the casing (2) and that provides the refrigerant coming from the evaporator to be received into the casing (2), a suction muffler (10) that is disposed into the casing (2) and that provides the noise originating due to the refrigerant to be attenuated and a passage pipe (4) that is disposed on the suction muffler (10) and one end of which is positioned almost across from the end of the inlet pipe (3) opening into the casing (2) ( Figure 1, Figure 2).
• the refrigerant coming from the evaporator After entering into the casing (2) by means of the inlet pipe (3), the refrigerant coming from the evaporator enters into the passage pipe (4) that is almost at the same level with the inlet pipe (3), and is delivered to the suction muffler (10) from there.
• the compressor (1) of the present invention comprises a protection member (5)
• the protection member (5) closes the mouth of the inlet pipe (3) and/or the passage pipe (4) without requiring any intervention and prevents oil from entering therein.
• oil is prevented from being pumped into the cooling system, when the compressor (1) is brought to a position parallel to the floor and operated. Consequently, the cooling efficiency of the compressor (1) and the cooling device wherein the compressor (1) is used is increased, thereby prolonging the life span of the components. Since oil is prevented from entering into the cooling cycle when the compressor (1) is inclined, the compressor (1) can be transported by being tilted to one side and transportation costs for products, such as cooling devices wherein the compressor (1) is used, decreases ( Figure 2, Figure 3, Figure 5).
• the protection member (5) comprises a shaft (6) that intersects the inlet pipe (3) and/or the passage pipe (4) vertically, a circular lid (7) that is mounted to the part of the shaft (6) remaining inside the inlet pipe (3) and/or the passage pipe (4) so that its diameter line coincides with the shaft (6), and a block (8) that is mounted to the end of the shaft (6) remaining outside the inlet pipe (3) and/or the passage pipe (4) and that moves the shaft (6) so that the lid (7) closes the mouth of the inlet pipe (3) and/or the passage pipe (4) when the casing (2) is brought to the inclined position.
• the diameter of the lid (7) is almost equal to the diameter of the inlet pipe (3) and/or the passage pipe (4) whereon the lid (7) is disposed.
• the shaft (6) coincides with the diameter line of the cross-section of the inlet pipe (3) and/or the passage pipe (4).
• the protection member (5) comprises at least two stoppers (9) that limit the movement of the block (8) and provide the lid (7) to remain between a first position (P1) wherein the lid (7) is positioned so as to almost entirely closes the mouth of the inlet pipe (3) and/or the passage pipe (4) and a second position (P2) wherein the lid (7) is positioned so as to be perpendicular to the cross-section of the inlet pipe (3) and/or the passage pipe (4).
• the lid (7) is prevented from moving further from the first position (P1) and opening the mouth of the inlet pipe (3) and/or the passage pipe (4), thereby oil is prevented from entering therein.
• the lid (7) changes to the first position (P1), and thus oil is prevented from entering into the inlet pipe (3) and/or the passage pipe (4) ( Figure 4, Figure 6).
• the protection member (5) prevents oil from entering into the inlet pipe (3) and/or the passage pipe (4).
