Decrease pressure to prevent excessive velocity
Anti-polishing rings are used to prevent carbon build-up in the cylinder liner. The carbon polishes the cylinder liner leaving it with a smooth surface. A smooth cylinder liner is bad because the lube oil won't be able to stick to the liner.
The function of back pressure valve is to prevent back flow to the pump in case there is an obstruction on downstream side of valve.
The purpose of both the valves is same - that to maintain a certain level(in a vessel or tank...) Simple Level valve could be referred to an ON - OFF valve where as control valve could be referred to an analog type of valve. On - OFF valve is for a crude control of level, while control valve is used where a fine level control is needed.
Most likely, it's normal operation. Most vehicles have what's called a cycling clutch compressor. A sensor bulb detects when the system reaches the predetermined high pressure limit, and disengages the compressor clutch to prevent overpressure in the AC system. When the system pressure drops to the predetermined low pressure, it reengages the compressor clutch.
Air pressure is all around you. Atmospheric pressure is the weight of earth's atmosphere. Nowbody can prevent this.

No. This idea is generally considered an old wives tale, as most cars' passenger compartments are not airtight.

In case of emergency, if the cylinder stops, the motor does not. So it can be harmful for motor. Designers couple the high power motor to the cylinder of pump by means of a clutch. so the motor can continue to rotate while the cylinder stops. Also in case of closing the outlet valve of a pump, the pressure in the cylinder can fail the cylinder or crankshaft and accessories. in this case the clutch can separate the power from motor to the pump and prevent failure of pump.
Direct pressure generally applies to the force applied to a wound to prevent bleeding
Located in master cylinder and prevent air from being drawn in past the wheel cylinder cups when the brakes are released
They help prevent pressure cracks in the deck and help prevent wheel contact with your graphic.
Ears "pop" when there is a change in pressure. It is the bodys way to prevent discomfort from pressure changes.
