What is a Piston Ring Compressor?

A piston ring compressor is a compressor that features pistons fit inside of a cylinder using compression rings that seal between the piston and cylinder wall. The piston moves up and down by use of a connecting rod attached from the piston to a crankshaft. Piston Ring compressors are usually oil lubricated in order to enable the rings to slide easily slide against the cylinder walls. Piston rings are usually made from a machined aluminum ring or spring steel. At BOGE, we provide the design and manufacturing of various types of compressor technologies, including piston ring compressors.

Piston Rings in a combustion engine or motor

As the part of a piston driven combustion engine or motor piston rings act similar as in an air compressor. Piston rings makes contact with the cylinder walls and also produce compression that is necessary to make a piston combustion engine operate. These piston rings, which are manufactured from spring-like material, must be tightly squeezed in order to fit inside the walls of the cylinder.

Installing a Piston & Rings in Piston Ring Compressor

A technician will slip the piston inside of the cylinder wall by compressing the expanded piston rings. The rings of the piston expand out of the ring grooves of the piston press securely against the cylinder walls of the compressor.

During the placement of the piston rings onto the piston, the gaps present in the end of the piston rings are staggered in order so they do not match perfectly with each other. This produces an increased cylinder compression that produces increases efficiency while minimizing any oil carryover.

Place the piston with rings at the top the cylinder with a ring compression tool flush with the cylinder block, the piston is then ready to be tapped into the cylinder with a soft, sturdy object such as a wooden handle hammer.

The piston and ring assembly should slide freely inside the cylinder as it is installed. The connecting rod is located inside the cylinder and connects the piston to crankshaft and should be positioned so the top of the piston is just slightly lower than the top of the cylinder when fully extended.
