Abstract
A pumping system includes a head having an opening and an injection port. The head is for holding content to be forced through the injection port. A bladder is within the head. The bladder is between the content and the opening. A plunger is configured to move through the opening of the head and to apply force within the bladder. The plunger may be movable in a discharge stroke to force the bladder against the content and thereby force the content through the injection port.
Claims19
A pumping system comprising:
- a head comprising an opening and an injection port, the head being configured for holding content to be forced through the injection port;
- a bladder within the head, the bladder between the content and the opening;
- and
- a plunger configured to move through the opening of the head and to apply force within the bladder, the plunger being movable in a discharge stroke to force the bladder against the content and thereby force the content through the injection port;
- and
- a driver to control the movement of the plunger, the driver for controlling the movement of the plunger so that the discharge stroke of the plunger proceeds for a first duration, a suction stroke of the plunger proceeds for a second duration, and the first duration exceeds the second duration,
- where the first duration is at least one order of magnitude greater than the second duration.
4 more elements
A pumping system comprising:
- multiple pumps, each of the multiple pumps being configured to inject content into a different target, the multiple pumps comprising respective plungers that are controllable to move to control injection of the content;
- and
- a driving mechanism configured to provide common control over the plungers to control injection of the content;
- where the driving mechanism is configured to control at least one of the plungers so that a discharge stroke of the at least one plunger proceeds for a first duration, a suction stroke of the at least one plunger proceeds for a second duration, and the first duration exceeds the second duration, and
- where the first duration is at least one order of magnitude greater than the second duration.
