His law gives the relationship between pressure and volume if temperature and amount are held constant If the volume of a container is increased, the pressure decreases If the pressure in a container is decreased, the volume increases Pressure x Volume = Constant P 1 V 1 = P 2 V 2 Boyles Law for gasses:
Consider two chambers, housing two pistons, connected by a shaft. Since the stroke of the piston in both chambers is equal, Boyles Law states that the ratio of Pressure to Area in both chambers is equal P1A1P1A1 P2A2P2A2 If the pressure on the left (P 1 ) is 80 psi and the area is 10 in 2, the resulting pressure in the right chamber will depend on the area (A 2 ). If A 2 is 1 in 2, than P 2 will be 800 psi
2 u 1 u 10 u PUSHING EXH CVS1 2 u 1 u 10 u PULLING EXH Double Acting Principle Pushing Air at 100 psi enters the left air cylinder chamber (air piston area = 10 in 2 ) pushing it to the right. The hydraulic piston is 2.0 in 2 and the rod is 1.0 in 2. Since the crossover check valve allows oil to flow into the rod chamber, the effective area pushing is the rod area, yielding a 10:1 air to hydraulic ratio. Pulling Air at 100 psi enters the right air cylinder chamber pushing it to the left (pulling the hydraulic piston). The pull ratio is also 10:1 as determined by the differential area in the hydraulic piston and rod. Note also during this stroke, oil is being drawn into the piston end for the next push stroke.

Summary of Principles Fluid pressure in times the ratio equals maximum fluid pressure out in a stalled condition The ratio of areas determines the output pressure The same principle (Boyles Law) applies for all pump products including the Vac-Pak The larger the ratio, the less flow that will be achieved Click next slide to start over…
