The pressure strike me as too high to be a major leak, there probably still is some liquid in the system somewhere for that kind of pressure. As the compressor shaft rotates, the vanes and housing form chambers. When the compressor runs , the swash plate which rotate with the shaft wobbles a little. Pressure vents from the discharge cavity high-side to the wobble plate case, increasing housing pressure. A wide variety of harrison v5 compressor options are available to you, There are 86 harrison v5 compressor suppliers, mainly located in Asia.

Sad to say, due to lack of time, facing the hotest temps of the year high 90s , and this being the car the spouse drives every day I took it to a mechanic I trust. This increase in capacity displacement continues until the swash plate is at the maximum angle position. Q4: Can I buy 1 piece of each item to test the quality9 Yes, we are pleased to send you 1 piece to test the quality if we have stock for the item you need. Two different types of control valve are used; mechanical and electronic. This reduces the angle of the swash plate and shortens the stroke, reducing displacement. On each suction stroke of the pistons, a small volume of refrigerant is sucked into the compression chamber through the suction reed valve, which is then pumped out into the discharge chamber through the discharge reed valve on each compression stroke of the pistons.
Note the wiring harness of the solenoid actuator Fig. In this rather lengthy video, I teardown a Delphi Harrison V5 air conditioning compressor. Variable stroke — Harrison V5 The Delphi Harrison V5 compressor is a non- cycling variable displacement compressor. My kits were older; whereas the newer ones are available complete. The compressor features a variable angle wobble plate in five V5 cylinder axial piston design. They have basically the same internal structure. Alternate Control valve required for R134a.
Through regulation of compressor crankcase pressure, the wobble plate angle, and therefore compressor displacement is variable. As the movable spiral oscillates within the fixed spiral, a number of pockets are formed between the spiral. As evaporator temperature decreases, so does low-side pressure. HubPages Traffic Pixel This is used to collect data on traffic to articles and other pages on our site. During idle an occasional vane noise from the compressor may be heard. As these pocket s decrease in size the refrigerant is squeezed, the pressure increases and is discharged through a reed valve at the discharge port in the rear section of the compressor.
If the product does not work properly as described, and proven to be at our fault, we will provide exchange services only for the same specific item. As the front shaft turns the wobble plate angle changes, causing the pistons to move in and out, pulling refrigerant vapor in through the suction side, compressing it and discharging this high-pressure vapor into the condenser. With regards to the 'tick over', there are a number of possible causes. General There are various makes and types of compressors used in automotive air conditioning systems operating on R134a. At maximum displacement, compressor crankcase pressure is equal to the compressor suction pressure. It takes 3 cans of R134a, which would have been recovered from the existing charge.
This increases the pressure at the discharge chamber of the compressor, while reducing the pressure at the suction chamber. Akismet This is used to detect comment spam.

To locate a member repair shop in your area. The process is straightforward to teardown, refurbish, and re-assemble the compressor. This results to a very smooth operation and improvement in fuel consumption. When the cabin is warm, evaporator temperature increases, which increases low-side pressure and collapses the diaphragm.

These compressors are very durable because they contain their own lubrication oil reservoir. The gauge set I have has an outside ring of temps which corresponds to the vapor pressure of 134a at various temperatures for the system as a check for general overcharge. At reduced or minimum displacement, the compressor crankcase pressure is greater than the suction pressure.

We frequently receive systematic training from professional consulting organizations and keep a sustainable growing of group skills. Using a manifold gage, you will notice that as the engine is revved up the pressure at the low side starts to rise and that of the high side starts to decrease. Lesser engine power requirement means lesser fuel consumption.
There may be a number of reasons why this is so, but one thing is sure. HubPages ® is a registered Service Mark of HubPages, Inc. If your compressor spins freely, has equal pressures on high and low sides while engaged at engine speed, the control valve may be the problem. At idle cooling is just right. The internal design could be Piston, Scroll, Wobble plate, Variable stroke or Vane. When they don't have good valves, they use new ones, which are set at the mid range.
