Definitions
- the field of application of the invention extends primarily to oil-free piston compressors in multi-cylinder design, which operate in one stage even at high operating pressures, wherein the cooling of the cylinder is performed via a cooling air flow.
- Compressors of the type described above required, which work reliably with little effort in the smallest space at extreme ambient temperatures and with a LK: hv Low maintenance cover a high air requirement.
- oil-free compressor concepts no oil filling of the compressor housing in the conventional sense is more available.
- the lubrication on the piston raceways is replaced by a low-friction piston coating.
- the rotating parts are supported by roller bearings with temperature-resistant, long-lasting grease filling. In the valves also guided parts are avoided, which could generate frictional heat.
- the advantage of the solution according to the invention manifests itself in particular in that piston and piston ring wear as well as the wear of the lubricants at the bearing points on all cylinders are uniformly low.
- the air-cooled piston compressor according to the invention achieves long service lives without maintenance, so that the overhaul intervals of the vehicle or the vehicle life are achieved even without replacement.
- the compressor of the piston compressor according to the invention can be performed oil-free and produces so far advantageous oil-free compressed air, which solves the hitherto commonly occurring in commercial vehicle Verkölungs- and coking problem in the brake system.
- the freedom from oil of the compressor also solves the problem of condensate removal and emulsion binding in the oil.
- the air-cooled piston compressor according to the invention can be used in commercial vehicles, since this is characterized by a sufficiently high power density at high speeds.
- cooling air duct along the flow direction constant in order to produce a uniform flow of cooling air, but to selectively select different cross-sections.
- the cylinder which is closest to the fan, by cross-section throttling a experience reduced cooling air supply, so that remaining cylinders, which are arranged further away from the fan, receive approximately the same cooling air as said closer cylinder.
- This advantage can be implemented solely by appropriate dimensioning of the cooling air forming component.
- such a cooling air channel should be formed by a two-part plastic housing, the halves of which can be easily produced in molds with a simple mold division, preferably by injection molding.
- the cooling air can also be divided evenly into chambers and components to be cooled within the crankcase.
- cooling air duct with regard to the most compact possible structural adaptation to the existing geometric dimensions of the compressor, possibly other sound insulation measures can be taken, for example by integration of sound insulation materials. These can also cover other sound-emitting components of the crankcase, in particular cylinder heads and crankcases.
- the fan 4 is arranged on a driven by the motor 3 and passed through to the compressor 2 common connecting shaft 5, about which the fan 4 rotates at the engine speed to suck cooling air from the environment and to promote in a fan 4 subsequent cooling air duct 6.
- the cooling air duct 6 which completely surrounds the cylinders 1a and 1b in the further course is designed so that the two cylinders la and lb of the compressor 2 arranged in series are uniformly circulated with cooling air as described above.
- the cooling air duct 6 forwards the used cooling air in the flow direction downstream of the two cylinders 1a and 1b into a common exhaust air duct, from where the used cooling air is brought together to the outside.
