[ We claim:] [1.] In combination, an operating mechanism and a device for precise replacement of liquid in an operating mechanism, comprising:the operating mechanism which can contain a liquid; andin communication with the operating mechanism, the device for precise replacement of liquid in the operating mechanism, which device includes:a plurality of flexible bags, each for containment of liquid, at least one of which flexible bags is adapted for containment of a liquid to be discharged and at least one of which flexible bags is adapted for containment of a liquid to be collected, the flexible bags being in contact, wherein the contact is selected from the group consisting of direct contact and indirect contact, so that an inter-bag diaphragm can be effectively formed with respect to the flexible bags;at least one inlet port in conjunction with each of the at least one flexible bag adapted for containment of a liquid to be collected, the at least one inlet port being capable of communicating with the interior of each of the at least one flexible bag adapted for containment of a liquid to be collected; andat least one outlet port in conjunction with each of the at least one flexible bag adapted for containment of a liquid to be discharged, the at least on outlet port being capable of communicating with the interior of each of the at least one flexible bag adapted for containment of a liquid to be discharged;such that when liquid is collected in the at least one flexible bag adapted for containment of a liquid to be collected, the at least one flexible bag adapted for containment of a liquid to be collected immediately applies discharge pressure to the at least one flexible bag adapted for containment of a liquid to be discharged, and, simultaneously, when liquid is contained in the at least one flexible bag adapted for containment of a liquid to be discharged, and with the at least one outlet port being left open to communicate to the exterior through the at least one outlet port, liquid contents of the at least one flexible bag adapted for containment of a liquid to be discharged can be expelled through the at least one outlet port left open;such that the precise replacement of liquid in the operating mechanism, when the operating mechanism is in liquid communication with the device and when the device is working to replace the liquid, is controlled by liquid pressure from used liquid from the operating mechanism, which used liquid is the liquid which then enters in the at least one flexible bag adapted for containment of a liquid to be collected of the device; andsuch that, when the device is working to replace the liquid, the liquid is replaced during normal operation of the mechanismand wherein each said liquid is at least one of a lubricant and an additive therefor.
