Definitions

  • the present invention relates to a refrigerant compressor including a compressor housing with a compressor housing base and a compressor housing cover, which compressor housing hermetically encloses a cylinder housing and a drive assembly, the refrigerant compressor further comprising a cylinder and a piston which are arranged inside the cylinder housing, said piston being drivable by the drive assembly, in order to move back and forth in the cylinder for compressing a refrigerant, the cylinder housing being mounted at the compressor housing base by means of at least one spring element, in order to allow for a movement and to damp vibrations of the cylinder housing, wherein a ring-shaped element is provided, which is rigidly connected to the cylinder housing and is arranged between the cylinder housing and the compressor housing cover, and wherein a cover pin is provided, which is rigidly connected to the cylinder housing cover and is extending into an annular recess of the ring-shaped element, in order to limit the movement of the cylinder housing.
  • a ring-shaped element which is rigidly connected to the cylinder housing and which cooperates with a cover pin, which cover pin is rigidly connected to the compressor housing cover.
  • a refrigerant compressor including a compressor housing with a compressor housing base and a compressor housing cover, which compressor housing hermetically encloses a cylinder housing and a drive assembly
  • the refrigerant compressor further comprising a cylinder and a piston which are arranged inside the cylinder housing, said piston being drivable by the drive assembly, in order to move back and forth in the cylinder for compressing a refrigerant
  • the cylinder housing being mounted at the compressor housing base by means of at least one spring element, in order to allow for a movement and to damp vibrations of the cylinder housing
  • a ring-shaped element is provided, which is rigidly connected to the cylinder housing and is arranged between the cylinder housing and the compressor housing cover, and wherein a cover pin is provided, which is rigidly connected to the compressor housing cover and is extending into an annular recess of the ring-shaped element, in order to limit the movement of the cylinder housing
  • rubber material includes any natural or synthetic rubber, e.g. fluoroelastomers or fluoropolymers.
  • the rubber material is a nitrile butadiene rubber (NBR) material.
  • the ring-shaped element Since the ring-shaped element is arranged inside the compressor housing, the ring-shaped element can come into contact with oil and refrigerant. Moreover, temperatures inside the compressor housing may become relatively high. In order to further improve the endurance of the NBR material of the ring-shaped element under these harsh conditions, in a preferred embodiment of the refrigerant compressor according to the present invention, it is provided that the nitrile butadiene rubber material is hydrogenated nitrile butadiene rubber.
  • Hydrogenated nitrile butadiene rubber keeps its favourable properties, like its resilience, also after long-term exposure to heat, oil and chemicals. Moreover, the tensile strength of HNBR can be fine tuned by filler selection and loading.
  • the cover pin is coated with or is made of a second rubber material.
  • the second rubber material can be identical with or can be different from the rubber material.
  • the second rubber material is a second nitrile butadiene rubber (NBR) material.
  • NBR nitrile butadiene rubber
  • the second NBR material can be identical with or can be different from the NBR material.
  • the cover pin is arranged inside the compressor housing, also the cover pin can come into contact with oil and refrigerant. Again, temperatures inside the compressor housing may become relatively high.
  • the second nitrile butadiene rubber material is a second hydrogenated nitrile butadiene rubber.
  • the second HNBR can be identical with or can be different from the HNBR.
  • the cylinder housing can move inside the compressor housing vertically, i.e. parallel to a vertical direction, as well as laterally, i.e. parallel to a lateral direction.
  • the cover pin extends into the annular recess parallel to a vertical direction, in order to limit the movement of the cylinder housing parallel to a lateral direction, the lateral direction being normal to the vertical direction.
  • the vertical movement of the cylinder housing can then simply be delimited by the compressor housing, i.e. when the ring-shaped element contacts an inner surface of the compressor housing, particularly of the compressor housing cover.
  • the compressor housing cover comprises an inner surface, the inner surface comprising a section next to the ring-shaped element, which section is coated with a third rubber material.
  • said section of the inner surface is facing towards the ring-shaped element.
  • the third rubber material can be identical with or can be different from the rubber material and/or the second rubber material.
  • the third rubber material is a third nitrile butadiene rubber (NBR) material.
  • the third NBR material can be identical with or can be different from the NBR material and/or the second NBR material.
  • the third nitrile butadiene rubber material is a third hydrogenated nitrile butadiene rubber.
  • a rigid holder is provided for connecting the ring-shaped element to the cylinder housing, the holder having a recess delimited by a surrounding section of the holder, wherein a section of the ring-shaped element is imposed on the surrounding section of the holder such that the annular recess of the ring-shaped element is arranged within the recess of the holder.
  • Fig. 1 shows a sectional view of a refrigerant compressor 1 according to the invention at hand.
  • the refrigerant compressor 1 can be mounted to an appliance with a cooling cycle, in which the refrigerant compressor 1 is placed, by means of support assemblies 21.
  • a compressor housing 2 which comprises a compressor housing base 3 and a compressor housing cover 4 for closing the compressor housing base 3, hermetically encloses a cylinder housing 5 which is mounted on a drive assembly 6.
  • this drive assembly 6 is realised as an electric motor which drives a crankshaft 22 and a piston rod 23 connected to a piston 8 in a cylinder 7 of the cylinder housing 5, in order to move said piston 8 back and forth in the cylinder 7 along a cylinder axis 20 for compressing a refrigerant.
  • a cylinder cover 10 is attached to the cylinder housing 5 while being separated from the cylinder 7 by a valve plate 9.
  • the valve plate 9 comprises an inlet valve (not shown) for drawing refrigerant from an inlet channel (not shown) into the cylinder 7 and comprises an outlet valve (not shown) for discharging the compressed refrigerant into a discharge channel (not shown).
  • the cylinder housing 5 - and hence also the drive assembly - is mounted at the compressor housing base 3 by means of spring elements 11.
  • the spring elements 11 allow for a movement of the cylinder housing 5 and damp vibrations of the cylinder housing 5, which vibrations occur due to the reciprocating and compressing piston 8 in the cylinder 7 when the refrigerant compressor 1 is in an operational state.
  • a counter weight 24 mounted on the crankshaft 22 helps reducing the vibrations.
  • a ring-shaped element 12 is provided, which is rigidly connected to the cylinder housing 5 and which cooperates with a cover pin 13, which cover pin 13 is rigidly connected to the compressor housing cover 4.
  • the actual shape of the ring-shaped element 12 can be particularly well discerned in the schematic axonometric view of Fig. 2 .
  • the cover pin 13 is extending into an annular recess 14 of the ring-shaped element 12. Hence, at a certain amplitude of movement of the cylinder housing 5 the ring-shaped element 12 is contacting or impacting on the cover pin 13, which limits the movement of the cylinder housing 5.
  • the ring-shaped element 12 is coated with or made of a rubber material, particularly of a resilient nitrile butadiene rubber (NBR) material.
  • NBR nitrile butadiene rubber
  • the NBR material is made of hydrogenated NBR (HNBR), which keeps its favourable properties, like its resilience, also after long-term exposure of the ring-shaped element 12 to heat, oil and chemicals, which exposures can take place inside the compressor housing 2, particularly during the operational state of the refrigerant compressor 1.
  • HNBR hydrogenated NBR
  • the cover pin 13 is made of metal or a rigid plastic.
  • the cover pin 13 can be coated with or made of a second rubber material, preferably of a second NBR material, particularly of a second HNBR.
  • the cover pin 13 extends into the annular recess 14 parallel to a vertical direction 15. Hence, the movement of the cylinder housing 5 is limited parallel to a lateral direction 16 when the ring-shaped element 12 contacts the cover pin 13, with the lateral direction 16 being normal to the vertical direction 15.
  • the inner surface 18 comprises a section 19 next to the ring-shaped element 12, which section 19 is coated with a third rubber material, preferably with a third NBR material, particularly with a third HNBR. As can be seen in Fig. 1 , said section 19 of the inner surface 18 is facing towards the ring-shaped element 12.
  • a rigid holder 17 is provided for connecting the ring-shaped element 12 to the cylinder housing 5.
  • the holder 17 is made of metal or a rigid plastic.
  • the holder 17 has a recess delimited by a surrounding section of the holder 17, wherein a circumferential section of the ring-shaped element 12 is imposed on the surrounding section of the holder 17 such that the annular recess 14 of the ring-shaped element 12 is arranged within the recess of the holder 17.
