What is a swash plate compressor?
The swash plate is an elliptical disc that is mounted at an angle to the compressor drive shaft. The rotation of the swash plate moves the pistons parallel to the drive shaft. Another component called a slipper disc slides on the swash plate, and a ball rides in a socket in the slipper disc.
How does the swash plate type compressor draw in refrigerant?
Swash Plate Type Compressor a swash plate mounted diagonally on a shaft. As the shaft rotates, the swash plate that is integrated with the shaft converts this rotational movement into reciprocating movement of the pistons, which draw and compress the refrigerant gas.
What controls the angle of the swash plate in a variable swash plate compressor?
The swashplate angle is controlled with linkage and springs, which are adjusted by changing the refrigerant pressure in the compressor housing. A control valve with ports and passages that connect to the suction (low-side) and discharge (high-side) chambers of the compressor head is utilized.
What is the angle between swash plate and stroke?
The typical swashplate angle chosen for this application is 40 degrees, enabling the radar to scan a total angle of 200 degrees out of 360.
How does a rotary compressor work?
Rotary screw air compressors operate by trapping air between two meshed rotors and reducing the volume of that trapped air as it moves down through the rotors. This reduction in volume results in compressed air, which can then be used to power air tools, inflate tires, or in numerous other applications.
How does a truck AC compressor work?
The compressor pumps, or forces, the liquid from the evaporator into a condenser and expansion valve, and then back to the evaporator. The engine drives the compressor with a belt. In action, the compressor takes the low pressure refrigerant from the evaporator and compresses it according to speed and air temperature.
How does a vehicle AC compressor work?
An AC compressor runs off a pulley that’s attached via a belt to the crankshaft of your engine. This powers 5-10 pistons (depending on the design). They suck in low-pressure, low-temperature gas and compress it into high-pressure, high-temperature gas.
What is the purpose of swash plate in a piston pump?
Swash plate angle controls the output flow of the pump. Swash plate angle is controlled by the force generated against the swash plate by the pumping pistons and by the force of the servo piston. The force of the servo piston is greater than the force of the pumping pistons when both are at the same pressure.
What is swash angle?
Which type of displacement is observed in swash plate piston pumps?
Variable displacement
Variable displacement. Movement of the swash plate controls pump output from zero to maximum.
