Definitions
- the invention relates to a refrigerant compressor, comprising a compressor housing, at least one in the compressor housing arranged cylinder chamber, one in the cylinder chamber oscillating piston, one of the cylinder chamber upstream suction chamber from which refrigerant in the cylinder chamber enters, one downstream of the cylinder chamber Pressure chamber in which in the cylinder chamber compressed refrigerant enters, and one of the pressure chamber downstream outlet duct.
- Such refrigerant compressors are from the prior art Technology known.
- the invention is therefore based on the object of a refrigerant compressor to improve the generic type in such a way that an effective damping of Pulsations is possible.
- This task is the beginning of a refrigerant compressor described type according to the invention solved in that compressed refrigerant through a damper duct from the Pressure chamber flows into the outlet channel that an inlet opening of the damper channel with a cross-sectional jump in the pressure chamber opens and that an outlet opening of the damper duct with a cross-sectional jump opens into the outlet channel.
- This concept according to the invention has the great advantage that a damping element to be provided in the lines is eliminated, so that additional pipe connections to install this Damping element are eliminated and that also the damper channel works optimally, since all pulsations are directly in the area their creation, namely in the pressure chamber of the refrigerant compressor dampens while a provided in the lines Damping element always has the disadvantage that even then, if it works optimally, is able to where it is arranged to dampen the pulsations as before, however, up to the damping element the undesirable Pulsations occur and unwanted noises and others Cause interference.
- the decoupling between the damper channel and the Pressure chamber also favored that the cross-sectional jump at least between the damper duct and the pressure chamber is a factor of 5, in which case a cross-sectional jump from the large cross section of the pressure chamber a cross section smaller by a factor of 5, namely the the inlet opening of the steam channel.
- the pressure chamber has a buffer volume, which pressure vibrations of the compressed refrigerant dampens and therefore ensures that the cylinder chambers relate to the pressure chamber compressed refrigerant supplied is not too large Pressure vibrations or pulsations in the pressure chamber leads.
- the buffer volume is like this is large that there are pressure vibrations so far dampens that it has a maximum amplitude of 20% have a mean outlet pressure.
- the outlet channel a buffer volume to dampen pressure vibrations or Forms pulsations.
- the outlet channel has an outlet chamber with a buffer volume.
- the outlet chamber is preferably also dimensioned in such a way that the buffer volume pressure fluctuations so far dampens that this has a maximum amplitude of 20% have a mean outlet pressure. Is particularly cheap this solution is preferred when following the outlet duct flanged to the compressor housing, a valve provided is so that the outlet channel with the outlet chamber as a whole forms a volume in which pressure vibrations could build up or in what pressure vibrations through the above buffer volume can be damped.
- damper channel itself extends over its entire length in the damper tube, so that the damper tube as an additional part in the compressor housing is inserted.
- the damper tube can be arranged, for example, that it extends into the pressure chamber.
- the outlet chamber has a volume greater than about 1.5 times, better still more than 2 times the in this lying section of the damper channel.
- a solution that is particularly favorable in terms of its effect provides that the damper channel is designed so that in essentially the entire compressed refrigerant the damper duct flows through.
- damper channel in Area of a transition of the pressure chamber into the outlet channel Closure element between the pressure chamber and the outlet channel enforced.
- a closure element can in the simplest Case with a receiving the damper channel Shock tube connected collar.
- damper channel has a straight section.
- Such one straightened section of the damper duct has the great advantage that the damper tube receiving this is easy to use.
- the inventive solution that the damper channel has a curved portion.
- the curved one Section can in principle both in the outlet channel and in Pressure room.
- a particularly favorable solution provides that the curved Section of the damper channel in the cylinder head, in particular the same in the pressure chamber, since in particular the Pressure room anyway has a large volume, so that in in this case, the arrangement of the curved section therein is cheap.
- the pressure chamber in a cylinder head is arranged and such Cylinder head easy due to its removability Access to the pressure chamber and thus easy installation a damper tube with a curved section allowed.
- damper channel which the takes up the entire damper channel
- the damper channel is at least partially molded into the compressor housing.
- a particularly suitable place for this is the cylinder head of the Compressor housing in which the damper duct is easier Forms way, which on the one hand assembly is facilitated and on the other hand the possibility is created, the greatest possible length of the damper channel to accommodate.
- a particularly advantageous in terms of assembly Construction provides that the inserted in the cylinder head Damper channel arranged in a in the outlet channel Damper pipe continues.
- the inlet opening of the damper channel in point in any direction.
- the inlet opening the damper duct outlet valves arranged in the pressure chamber is. This is an advantageous inflow in particular of the compressed refrigerant into the damper tube guaranteed and thus ensured that the Pulsations of compressed refrigerant as close as possible already dampened in their place of origin by the damper tube or be compensated.
