Definitions
- Piston compressors in particular radial piston compressors
- the present invention relates to a piston compressor, in particular a radial piston compressor, according to the preamble of claim 1.
- a piston compressor is an element of fluid technology.
- the piston-working chamber combinations in a radial piston compressor are arranged radially and perpendicularly to the drive shaft.
- the conveying or lifting movement of each individual working piston is usually caused by an eccentric located on the drive shaft.
- the piston compressor in particular a radial piston compressor, comprises a plurality of piston/working chamber combinations which extend in a star shape and radially from the drive shaft.
- the radial piston compressor pumps a fluid from a low-pressure area into a high-pressure area.
- Piston compressors are used, for example, as compressors for coolants in air conditioning systems in motor vehicles, in particular also in electrically powered motor vehicles.
- Refrigerant compressors which work according to the piston principle, usually have two collecting volumes from which the sucked-in low-pressure gas (low-pressure area/LP) feeds and into which the compressed high-pressure gas (high-pressure area/HP) is pushed out.
- low-pressure area/LP low-pressure area/LP
- high-pressure area/HP high-pressure area/HP
- Both collection volumes can, for example, be guided in channels (annular channels or the like).
- the discontinuous intake at the inlet channel or inlet valve and the ejection at the outlet channel or outlet valve generate pressure pulsations in the respective collection volume, which can continue through the internal channels and the compressor connections into the refrigerant circuit. If the pulsation level is too high, e.g. the heat exchanger can lead to noise being emitted into the passenger cell.
- a piston refrigerant compressor is proposed in DE 11 2010 000 920 T5, for example, which has a refrigerant suction chamber and a refrigerant discharge chamber, as well as a refrigerant distribution device, which has a distribution line and bypass lines that connect the distribution line and the suction chambers of the compressor units associate.
- a refrigerant ejection device including a discharge line and bypass lines connecting the discharge line and the discharge chambers of the compressor units.
- the piston refrigerant compressor proposed here is characterized is characterized in particular in that the compressor further comprises pressure compensation means which are designed to connect the suction chambers of at least two compressor units and/or the discharge chambers of at least two compressor units.
- the object of the present invention is therefore to propose an improved piston compressor, in particular to propose a piston compressor that can be manufactured more easily and more economically.
- the low-pressure collection volume comprises a first partial collection volume and at least one second partial collection volume, the first partial collection volume and the second partial collection volume being fluidically connected to one another via a first overflow channel and at least one second overflow channel and/or the high-pressure collection volume comprising a first partial collection volume and at least one second partial collection volume , wherein the first partial collection volume and the second partial collection volume are fluidly connected to one another via a first overflow channel and at least one second overflow channel.
- the intake and/or exhaust collection volume in two parts, so that the fluid flows through both partial collection volumes of the low-pressure collection volumes before intake and/or both partial collection volumes of the high-pressure pressure collection volumes after compression.
- the transfer of the fluid between the partial collection volumes is realized by means of overflow channels.
- the two partial collection volumes are fluidically connected to one another by means of the overflow channels. Fluidly connected to one another means here that the fluid can flow through the respective channels, in particular from one partial collection volume into the other partial collection volume.
- the pulsations can spread and dampen or even extinguish.
- the transition channels as well as the partial volumes are preferably like this dimensioned so that a pulsation at the valve or inlet channel or outlet channel cannot continue or can only be dampened to the desired extent in the second partial collecting volume. In principle, this works for both the low-pressure range and the high-pressure range, so that it is not necessary to refer to it separately here. However, the reduction of pulsation is particularly relevant for the high-pressure range. Which damping (which order of the excited vibration) is to be eliminated or dampened can be determined individually and determined by the dimensions/arrangement of the first partial collection volume, the second partial collection volume and the overflow channels.
- the piston-working space combinations each comprise a piston and a working space, with the piston-working space combinations being arranged radially around a drive shaft.
- a piston compressor designed in this way, in particular a radial piston compressor, is suitable in a particularly advantageous manner for the proposed invention.
- the piston compressor includes a housing for accommodating the piston-working chamber combinations and a removable cover.
- the piston/working space combinations can advantageously be accommodated or partially formed from the housing via the housing.
- the partial collection volumes are ring-shaped, with the partial collection volumes being arranged in particular next to one another and/or in one plane.
- An annular configuration of the partial collection volumes preferably coaxially around the longitudinal axis, offers a space-saving configuration of the collection volumes.
- the partial collection volumes can be designed to be nested in one another and/or housing components can be used for their design.
- a separating element is arranged between the partial collection volumes, with the overflow channels being arranged in the separating element.
- a separate separating element enables easy Design and positioning of the overflow channels.
- different materials can be used for the separating element, which can take on application-specific tasks, for example sealing with a sealing material, forming the overflow channels with metal inserts, etc.
- the separating element comprises a separating area and a sealing area.
- the areas can be designed in a correspondingly specific manner depending on the requirements for the separating element.
- the low-pressure collection volume in particular the first partial collection volume
- the high-pressure collection volume in particular the second partial collection volume
- the low-pressure inlet being offset in the circumferential direction, in particular by Offset by 90° to the overflow channels of the low-pressure collection chamber and/or the high-pressure outlet is arranged offset in the circumferential direction, in particular offset by 90°, to the overflow channels of the high-pressure collection chamber. It has been shown that the 90° offset can achieve a good reduction in pulsation in many applications.
- the overflow channels are arranged in the high-pressure collection volume in such a way that they have the same distance from the high-pressure outlet channel or the fluid has the same path from both passages and/or that the overflow channels in the low-pressure collection volume are arranged in such a way are that they have the same distance to the low-pressure inlet channel or that the fluid has the same path from both passages. It has been shown that the same distance can be used to achieve a good reduction in pulsation in many applications.
- the position and number of overflow channels are designed or arranged according to possible resonant pressure fluctuations. In this way, a pulsation can be counteracted in the best possible way.
- the outlet valves and/or the fluid outlet channels are arranged axially or radially with respect to the longitudinal axis of the piston compressor. In principle, the invention can be used both in the case of radially and also axially aligned outlet valves or fluid outlet channels.
- the separating element comprises different materials, in particular that the separating element comprises sealing material and overflow channels vulcanized on. In this way, the separating element can be optimally adapted to the respective application.
- the separating element is designed as an insertable component, in particular fixable in the collection volume or fixable on the housing.
