Description

A COMPRESSOR WHEREIN CYLINDER HOLE WITH DIFFERENT DIAMETER IS USED
The present invention relates to a compressor comprising a connection hole that is bored on the cylinder housing and that allows the use of cylinder hole with a different diameter.
In cooling devices, the circulation of the refrigerant liquid used for refrigeration is provided by a compressor. During the operation of the compressor, the rotational movement received from the motor is transferred to the piston with the crank-connection rod-crankpin mechanism. The pressure of the refrigerant fluid in the cylinder hole increases by being compressed with the reciprocating movement of the piston. High-pressure gas is delivered to the exhaust chamber by passing through the exhaust inlet with the opening of the exhaust leaf on the valve table. The gas in the exhaust chamber is sent to the suction muffler through a connection hole bored on the cylinder housing and delivered to the refrigerant fluid cycle by means of the vibration tube. The need for different capacity in the compressors is met by arranging a cylinder hole with a different diameter on the same cast cylinder housing.
In the state of the art, the connection hole is a channel extending between the face wall of the cylinder housing and the exhaust silencer. Although the minimum distance required between the cylinder hole and the connection hole is critical depending on the increase in the cylinder hole diameter, this distance required for the valve table gasket to provide leak-proofing cannot be provided. That the valve table gasket fails to provide leak-proofing between the connection hole and the cylinder hole causes leaks.
The aim of the present invention is the realization of a compressor wherein the sufficient minimum distance is provided by means of the connection hole bored in the same form for the cylinder hole in different diameters.
The compressor realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof comprises a connection hole that extends between the face wall of the cylinder housing and the exhaust silencer and that has a channel with one end opening to the exhaust silencer and a port extending between the other end of the channel and the face wall and having a diameter different than the diameter of the channel.
In an embodiment of the present invention, the connection hole is two-stepped and the width of the port is larger than the width of the channel.
In another embodiment of the present invention, the port has an almost conic inner surface that narrows from the face wall towards the channel.
In an embodiment of the present invention, the port is in the form of an almond or drop.
In another embodiment of the present invention, the compressor comprises an additional member that is mounted to the connection hole. The additional member comprises a tube that enters the channel and a headpiece that is seated into the port. The additional member comprises two different headpieces depending on the diameter of the cylinder hole. Thus, without changing the connection hole, the minimum distance required between the cylinder hole and the connection hole is always provided according to the diameter of the cylinder hole.
The model embodiments related to the compressor realized in order to attain the aim of the present invention are shown in the attached figures where

The compressor (1) comprises an upper casing (2) that covers the movable components and a lower casing (3) that contains the oil on the base thereof and that supports the components therein; a motor (4) that is composed of two components, that is a stator (5) and a rotor (6); a cylinder (7) that provides the pumping of the refrigerant gas; a cylinder housing (8); a piston (11) that enables the refrigerant gas to be compressed in the cylinder (7); a crank (10) that transfers the movement received from the motor (4); a connecting rod (12) that transfers the movement received from the crank (10) to the piston (11); a crankpin (13) that connects the connecting rod (12) and the piston (11) to each other; a bearing (9) that enables the crank (10) to be borne to the cylinder housing (8) in the radial direction, and an exhaust silencer (15) (Figure 1).
The compressor (1) furthermore comprises a connection hole (16)
  • that extends between the face wall (19) of the cylinder housing (8) and the exhaust silencer (15) and
  • that has
    • a channel (17) with one end opening to the exhaust silencer (15) and
    • a port (18) that is arranged between the other end of the channel (17) and the face wall (19) and that widens towards the face wall (19)
(Figure 2, Figure 3 and Figure 8).
During the operation of the compressor (1), the movement received from the motor (4) is transferred to the piston with the crank (10), the connection rod (12) and the crankpin (13). The pressure of the refrigerant fluid in the cylinder hole (7) increases by being compressed with the reciprocating movement of the piston (11). High-pressure gas is delivered to the exhaust chamber (14) by passing through the exhaust inlet with the opening of the exhaust leaf on the valve table. The gas in the exhaust chamber (14) is delivered to the exhaust silencer (15) through the connection hole (16) bored on the cylinder housing (8). By means of the stepped connection hole (16) comprising the channel (17) and the port (18), the critical minimum distance between the cylinder hole (7) and the connection hole (16). Thus, while the gasket provides the leak-proofing between the connection hole (16) and the cylinder hole (17), the leaks are prevented and the need for different capacity in the compressors (1) is provided by forming cylinder holes (7) in different diameters on the same cast cylinder housing (8).
In an embodiment of the present invention, the end of the port (18) connected to the channel (17) is circular and the end thereof opening to the face wall (19) of the cylinder housing (8) is elliptical. In the preferred embodiment of the present invention, the end of the port (18) opening to the face wall (19) of the cylinder housing (8) is in the form of an almond or drop.
In another embodiment of the present invention, the width of the port (18) is larger than the width of the channel (17).
In another embodiment of the present invention, the port (18) is in the form of a trapezoid with a short lateral side and a long lateral side.
In an embodiment of the present invention, the connection hole (16) extends between the face wall (19) of the cylinder housing (8) and the exhaust silencer (15) in an inclined manner.
In an embodiment of the present invention, the compressor (1) comprises an additional member (20) having a matching form with the connection hole (16) and disposed into the connection hole (16). By means of the additional member (20) disposed into the connection hole (16), sufficient minimum distance is provided for different diameters of the cylinder hole (7). Disposing the additional member (20) in the connection hole (16) at different positions for the cylinder holes (7) in different diameters enables the critical distance to be maintained. By means of the additional member (20), the minimum distance between the cylinder hole (7) and the connection hole (16) is enabled to be constant for every diameter.
Thus, the additional member (20) decreases the thermal conductivity between the cylinder housing (8) and the connection hole (16). n this case, since the temperature of the refrigerant fluid decreases, the efficiency of the compressor (1) is improved.
In an embodiment of the present invention, the additional member (20) comprises a preferably cylindrical tube (21) that is seated into the channel (17) and a headpiece (22) that is fitted into the port (18). The tube (21) and the headpiece (22) are disposed coaxially while the inner diameter of the tube (21) is equal to the inner diameter of the headpiece (22). The additional member (20) comprises two different headpieces (22) with changing wall thickness according to the width of the cylinder hole (7) (Figure 4, Figure 5, Figure 6 and Figure 7).
The headpiece (22) on the additional member (20) that is positioned in the connection hole (16) on the cylinder housing (8) with the large diameter cylinder hole (7) comprises a long lateral side and a short lateral side, and the wall thickness increases from the long lateral side to the short lateral side. When the additional member (20) with the said headpiece (22) is disposed into the connection hole (16), the headpiece (22) is perfectly fitted into the port (18) while providing a gap between the tube (21) and the channel (17). In this embodiment, the short lateral side of the port (18) is seated onto the short lateral side of the headpiece (22) while the long lateral side thereof is seated onto the long lateral side of the headpiece (22). In this embodiment, the port (18) and the cylinder hole (7) are tangential to each other and the critical distance between the cylinder hole (7) and the connection hole (16) is provided by means of the wall thickness of the headpiece (22) (Figure 9).
The headpiece (22) on the additional member (20) that is positioned in the connection hole (16) on the cylinder housing (8) with the small diameter cylinder hole (7) comprises a long lateral side and a short lateral side, and the wall thickness increases from the short lateral side to the long lateral side. When the additional member (20) with the said headpiece (22) is disposed into the connection hole (16), the headpiece (22) is perfectly fitted into the port (18) while providing a gap between the tube (21) and the channel (17). In this embodiment, the short lateral side of the port (18) is also seated onto the short lateral side of the headpiece (22) while the long lateral side thereof is seated onto the long lateral side of the headpiece (22) (Figure 10).
