Definitions

• This invention relates to a compressor comprising a valve plate made of different materials, which are used in household appliances particularly in refrigerators.
• the object of this invention is to provide a compressor for household appliances and particularly refrigerators comprising a valve plate for minimizing the noise by using different materials without reducing its function.
• Figure 1 - is a schematic cross sectional side view of a compressor.
• Figure 2 - is a perspective view of a valve plate assembly.
• Figure 3 - is a three dimensional view of a valve plate comprising a damper.
• Figure 4 - is an exploded view of a piston, a gasket, a suction valve sheet, a valve plate, an exhaust, a stop member and more than one pin.
• Figure 5 - is an exploded view of more than one gasket, a suction valve sheet, a damper, a frame, an exhaust valve sheet, a stop member, more than one pin, suction muffler, cylinder head and more than one fastener.
• the circulation of the cycle fluid is provided by means of a reciprocating hermetic compressor (1).
• the cycle fluid is used as a cooling gas.
• the compressor (1) comprises one or more casing (7) holding the components, a cylinder (8) in the casing (7) for pumping the cooling gas, a piston (9) on the cylinder for compressing the cooling gas into the cylinder opening, a crank (10) for transferring the motion of the motor, a piston rod (11) transferring the motion from the crank (10) to the piston (9), a suction muffler (12) preferably made of plastic material for allowing the cooling gas to reach at the cylinder (8) area before being heated and minimizing the noise which may be caused by the cooling gas, a cylinder head (13) connecting the suction muffler (12) and the cylinder (8), a valve plate (2) making a rigid and tight connection between the cylinder (8) and the cylinder head (13) and allowing the suction and compression of the cycle fluid, a suction valve sheet (3) on
• Naive plate (2) comprises a frame (6) made of preferably metal material and resistant to the axial loads, and a damper (5) in the frame (6) made of preferably a rigid plastic material for minimizing the vibration and the noise when the suction valve sheet (3) and exhaust valve sheet (4) strikes the top of the valve plate (2).
• the frame (6) and the damper (5) are attached to each other in an intermeshing way and, exhaust and suction trepans are provided with a plane form by means of grinding operation.
• the damper (5) has a size bigger than the diameter of the cylinder (8) to cover the cylinder and a position to allow the connection of the frame (6) to the cylinder (8) and the cylinder head (13).
• the damper (5) is pressed on the valve plate (2) by means of the injection method following the formation of the frame (6) from sinter or thin plate material.
• exhaust and suction trepans are provided with a plane form preferably through grinding operation.
• dampers (5) which are classified according to their thickness by measuring the progress of the piston (9) are used instead of the suction gasket (16) used for reducing the clearance space by optimizing the part of the piston (9) which is also known as the progress of the piston (9) projecting from the front surface of the cylinder (8).
• the use of the classified suction gasket (16) is not needed.
• the use of a suction gasket (16) having a fixed thickness is sufficient thereby reducing the cost of the suction gasket (16) and minimizing the variability in the cooling capacity caused by the variability in the thickness of the suction gasket (16) and the possibility of the attachment of a suction gasket (16) having an unacceptable thickness.
• the (2) of the compressor (1) comprises a suction sheet housing (50), a suction valve sheet (51) having a suitable form for the suction sheet housing (50) and one or more pins (52) having preferably an elliptic form for fixing the suction valve sheet (51) to the suction sheet housing (50) and to the valve plate (2) in a vertical direction and preventing its rotation to the left or right direction around the axis around which it is fixed.
• the suction gasket (16) comprises a pin housing (53) having a suitable form for preventing level differences which, may be caused by the pin (52).
• the suction valve sheet (51) is in a damper (5), which is bigger than the cylinder (8) and fixed by means of the pin (14). Thus it can be fixed in all directions only by a pin (14).
• a damper (5) having less thickness than the valve plate (2) is used with respect to the progress of the piston (9). Therefore the distance between the piston (9) and the suction valve sheet (3) is maintained.
• vibration and noise caused by the strike of the sheets (3, 4) preferably made of metal material to the valve table (2) preferably made of metal material like sinter or thin plate, are minimized.
