VEHICLE COMPRESSOR SERIES FK40/755 - EXPANSION FOR HOTTER CLIMATES
15 % MORE POWER AT THE SAME SIZE
With the most powerful version FK40/755, BOCK offers its customers 15 % more power with the same external dimensions. BOCK vehicle compressors are equipped with the K valve plate system as standard. They are ideally suited for bus air conditioning with increased cooling power requirements in city-, intercity and articulated buses or in areas with very warm ambient temperatures.
Compact lightweight
- Optimised heat dissipation due to ribbed surface
- Efficient over the entire speed range
Robust and powerful
- Robust crankshaft design with roller bearings on both sides: works extremely reliably and with high speed stability
-
Split screwed aluminium connecting rods: stable and robust, thus easy to handle
-
Reliable pressure lubrication with powerful oil pump independent of direction of rotation
-
Extremely low wear, thus extremely durable
-
Valve plate systems specially adapted to the field of application
VEHICLE COMPRESSOR WITH VALVE PLATE IN K-VERSION
Unique FK valve plate system specially developed for air- conditioning!
- Valve plate made of aluminium
- Working valves made of high-quality, impact-resistant spring steel
- Extremely robust and reliable in the face of speed and pressure fluctuations as well as exposure to liquids
- Long service life due to loosely guided annular discs which prevent bending and torsional forces
- Highest operational safety and efficiency
VEHICLE COMPRESSOR WITH VALVE PLATE IN N-DESIGN: FOR AIR-CONDITIONING AND NORMAL COOLING!
- For universal use in mobile applications
- Lamellas clamped on one side, which are exposed to bending and torsional forces; therefore limited load-bearing capacity at high speed and exposure to liquids
VEHICLE COMPRESSOR LOW TEMPERATURE VERSION WITH VALVE PLATE IN TK-VERSION
- Specially adapted version for low temperature cooling
- Valve plate TK design for low evaporating temperatures, based on the N-valve plate basic concept with torsionally stiff lamellas
- With additional measures for delivery rate optimization at low evaporating temperatures
- Piston crowns provided with grooves in the suction lamella contour: for further damage space minimization and increased performance in the low-temperature range
- Increased efficiency and performance in the low temperature cooling range
SPECIAL HOUSING K1 – APPLICATIONS FOR EURO 6
Due to special requirements by customers, there is a demand for additional fastening options on the compressor housing – particularly where there is little installation space available, as is the case in many Euro 6 buses. This has been achieved by means of the K1 special housing, which creates a higher level of stability thanks to the compressor being fastened directly to the vehicle motor.
Special features of the K1 housing:
- Optimized housing
- With intermediate flange 46 mm for suction and pressure shut-off valve
- Available models FKX40/470 K1, 560 K1, 655 K1 and 755 K1
- 6-cylinder compressor series FK50 with K1 housing with additional mounting points on request
