Abstract
A gas compression apparatus and method according to which a compression cylinder is connected between two heads, and gas is introduced into at least one header and into the cylinder. A piston is reciprocated in the cylinder with a stroke corresponding to the length of the cylinder to compress the gas after which the compressed gas is discharged from the cylinder. If the cylinder bore becomes damaged or wears out, or if it is desired to change the stroke length of the piston, the cylinder can easily be replaced by disconnecting it from the heads and installing another cylinder between the heads.
Claims29
A method for compressing gas comprising the steps of connecting a compression cylinder between two heads, introducing gas into at least one header, passing the gas from the header into the cylinder, reciprocating a piston in the cylinder with a stroke corresponding to the length of the cylinder to compress the gas, discharging the compressed gas from the cylinder, disconnecting the cylinder from the heads, and connecting another cylinder between the heads, the other cylinder having a different bore length than the first-mentioned cylinder to permit a different stroke length of the piston.
A method for compressing gas comprising the steps of connecting a compression cylinder between two heads, introducing gas into at least one header, passing the gas from the header into the cylinder, reciprocating a piston in the cylinder with a stroke corresponding to the length of the cylinder to compress the gas, discharging the compressed gas from the cylinder, disconnecting the cylinder from the heads, removing the cylinder from the two heads, and connecting another cylinder between the two heads, the other cylinder having a different bore than the first-mentioned cylinder.
A method for compressing gas comprising the steps of connecting a compression cylinder to a head, introducing gas into the head, passing the gas from the head into the cylinder, reciprocating a piston in the cylinder with a stroke corresponding to the length of the cylinder to compress the gas, discharging the compressed gas from the cylinder, disconnecting the cylinder from the head, and connecting another cylinder to the head, the other cylinder having a different bore length that of the first-mentioned cylinder to permit a different stroke length of the piston.
A gas compression kit comprising at least one head, two compression cylinders adapted to be selectively detachably connected to the head, and a piston adapted for mounting in either of the cylinders for reciprocal movement, the cylinders having the same diameter and different lengths to permit different stroke lengths of the piston.
