What is a piston?
Q: What is a piston?
A: A piston is a lubricated sliding shaft that fits tightly inside the opening of a cylinder.
Q: What is the purpose of a piston?
A: The purpose of a piston is to change the volume enclosed by the cylinder, to exert a force on a fluid inside the cylinder, to cover and uncover ports, or some combination of these.
Q: What is a rubber seal used for in a piston?
A: A rubber seal is sometimes used to keep the lubricate within the shaft.
Q: Why should the rubber seal be replaced with every servicing?
A: The rubber seal should be replaced with every servicing because due to the constant motion of the machine this seal wears quickly.
Q: What can happen if the rubber seal breaks during usage?
A: If the rubber seal breaks during usage there can be disastrous long-lasting consequences for the machine.
Q: Can a piston have more than one purpose?
A: Yes, a piston can have more than one purpose such as changing the volume enclosed by the cylinder, exerting a force on a fluid, and covering and uncovering ports.
Q: Is it important to keep the rubber seal in good condition?
A: Yes, it is important to keep the rubber seal in good condition as it helps to keep the lubricant within the shaft and prevent damaging consequences.
