Definitions
- the present invention relates to a hermetic compressor comprising a suction muffler which reduces the noise generated during the cycling of the refrigerant fluid used in the cooling cycle of cooling devices.
- a suction muffler that enables the refrigerant fluid used to provide cooling to reach the cylinder region without heating up and that provides the suppression of the noise that may originate from the refrigerant fluid is used.
- the suction muffler is generally produced from plastic material and disposed on the cylinder head or between the cylinder head and the valve table. The sucked refrigerant fluid passes through the suction muffler of which the part constituting the suction manifold is disposed in the cylinder head and reaches the cylinder.
- the cylinder head is produced as a single piece and a part of the cylinder head comes into contact with the surfaces of the suction muffler that constitute the suction chamber thereof. It is observed, however, in the compressors that the muffler head becomes loose and move in the gap of the cylinder head over the time. This is caused by wearing of the pins on the muffler head during mounting or operation. Consequently, the permanent contact between the muffler head and the valve table is broken and due to the vibrations of the motor, impacts may occur, thereby increasing the noise level of the compressor.
- the aim of the present invention is to realize a compressor wherein the noise is reduced by preventing the suction muffler from hitting the cylinder head and the valve table.
- 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 flexible protrusion that is produced from thermoplastic material as a single piece with the muffler head, that extends to contact the cylinder head and that serves as a spring.
- the protrusion is integrated with the rear wall of the suction muffler and pushes the head of the suction muffler toward the valve table.
- the protrusion serving as a spring By means of the protrusion serving as a spring, permanent contact between the suction muffler and the valve table is provided. Thus, even if the pins joining the muffler head and the cylinder head with each other are worn, permanent contact between the suction muffler and the valve table is provided, impacts are prevented and the noise level is reduced.
- the protrusion is preferably in the form of "J" and comprises a first arm and a second arm connected to the first arm. A curved bend is provided between the first arm and the second arm.
- Figure 1 - is a cross-sectional view of a compressor.
- Figure 2 - is a cross-sectional view of the muffler head on the suction muffler wherein the cylinder head and the valve table are also illustrated symbolically in order to provide information about the position.
- the compressor (1) comprises a motor (2) consisting of two main parts, a stator (3) and a rotor (4); a cylinder (5) providing pumping of the refrigerant fluid; a cylinder head (6) that is disposed on the cylinder (5) and that provides circulation of the refrigerant fluid at low and high pressures; a valve table (10) that enables the refrigerant fluid at low pressure to be taken into the cylinder (5) and the refrigerant fluid at high pressure to be delivered to the cylinder head (6); a suction muffler (7) that is disposed on the cylinder head (6), that is produced from thermoplastic material, that enables the refrigerant fluid to reach the cylinder (5) without heating up and that minimizes the noise, and a muffler head (8) that enables the suction muffler (7) to be mounted on the cylinder head (6).
- the suction muffler (7) in the compressor (1) of the present invention comprises a flexible protrusion (11) that is produced as a single piece with the muffler head (8), that extends from the muffler head (8) toward the cylinder head (6) to contact the latter and that provides continuous contact between the muffler head (8) and the valve table (10) during the operation of the motor (2) ( Figure 1, 2).
- the protrusion (11) is disposed between the suction muffler (7) and the cylinder head (6), on the rear wall of the muffler head (8) facing the cylinder head (6).
- the flexible protrusion (11) bearing on the cylinder head (6) pushes the muffler head (8) back, pressing the same toward the valve table (10).
- the protrusion (11) closes the gap between the muffler head (8) and the cylinder head (6), thus providing permanent contact between the muffler head (8) and the cylinder head (6) and between the muffler head (8) and the valve table (10), and preventing the muffler head (8) from hitting the cylinder head (6) and the valve table (10) due to the vibrations of the motor (2), and thereby the noise level is reduced.
- the protrusion (11) comprises a first arm (12) with one end connected to the suction muffler (7), a second arm (13) that is connected to the first arm (12) and that extends almost in parallel with the muffler head (8) and the cylinder head (6), and a bend (14) that connects the first arm (12) to the second arm (13).
- the protrusion (11) can be in either "J” form or ""L” form.
- the bend (14) has a curved structure and the protrusion (11) is preferably in "J” form in order to provide permanent contact between the muffler head (8) and the valve table (10) and to improve the springiness function.
- a gap (15) occurs between the muffler head (8) and the protrusion (11) which is fixed on the rear wall of the muffler head (8), and the second arm (13), hence the protrusion (11) stretches by means of the said gap (15).
- the protrusion (11) is produced as a single piece from the same material as the muffler head (8), use of an additional part is avoided and thus saving in terms of material and labor is achieved.
