Device to actuate a fluid connector contamination cover

摘要

A device to actuate a contamination cover on a machine bracket, the device comprising a master cylinder positioned on the machine bracket; a first slave cylinder positioned on the machine bracket and connected to the contamination cover; and a closed master-slave circuit connecting the master cylinder to the slave cylinder wherein the actuation of the master cylinder drives the slave cylinder for the transition of the contamination cover from a close to an open position.

1. A device to actuate a contamination cover on a machine bracket, the device comprising:
a master cylinder positioned on the machine bracket, the master cylinder comprising a master cylinder barrel and a piston connected to a master piston rod; a first slave cylinder positioned on the machine bracket, the first slave cylinder comprising a slave cylinder barrel and a piston connected to a slave piston rod, wherein the slave piston rod is connected to the contamination cover; and a closed master-slave hydraulic circuit connecting the master cylinder to the first slave cylinder wherein actuation of the master cylinder drives the first slave cylinder for transition of the contamination cover between a closed position and an open position, wherein the master-slave circuit comprises fluid lines configured to connect a piston side chamber of the master cylinder to a piston side chamber of the first slave cylinder and to move a volume of oil between the master cylinder and the first slave cylinder, and wherein the slave piston rod is one of retracted into or extended from the slave cylinder barrel and the master piston rod is the other of retracted into or extended from the master cylinder barrel when the contamination cover is in the open position.
