Abstract

Multiport pumps and associated pumping systems are described that provide a selective hydraulic or electrically powered pump/pump system. The pumps provide movement within a device or larger system. Movement can cause compression/expansion of a fluid and provide fluid movement within the same device or system. In this instance, the volume of fluid and the fluid flow path within, from, and to the pump(s) is kept constant to reduce or eliminate cavitation, seizure, and/or hydraulic lock. Use of at least one reservoir comprising; a compensator tank, a port allowing for operation at ambient pressure, and a pressure measuring device measuring pressure allowing for unbalanced flow to and from the multiport pumps along with thermal expansion or compression is detailed. In addition, use of a multiport swashplate pumps and associated valve plates that incorporate the features and functions of several valves not heretofore provided within the pump itself is also described.

Dependent claims

At least one multiport pump that pumps fluid in either a single or bi-directional direction having multiple ports comprising;

at least one inlet port, at least one outlet port, and at least one equilibrator port connected to a fluid reservoir wherein said equilibrator port equilibrates inlet and outlet flow such that a combination of said inlet port and said equilibrator port provide just enough fluid volume to fill one or more cavities of said at least one multiport pump so that fluid escapes through said outlet port to ensure overfill of said ports is prevented and so that a balanced equilibrium constant volume of fluid is maintained and resides within said at least one multiport pump during operation, wherein said at least one multiport pump withdraws and/or sends fluid into and out of said fluid reservoir to maintain a constant volume of fluid that reduces cavitation and hydraulic fluid lock and also provides and allows a balanced constant continuous fluid flow along a fluid flow path that contains fluid that flows in either a clockwise or counterclockwise direction into and out of said fluid reservoir that also acts as a constant volume compensator, such that an incremental volume of fluid is added or removed to maintain equal symmetric inflow and outflow of fluid into and out of said at least one multiport pump and wherein said fluid reservoir is vented, sealed, pressure compensated, preloaded and/or expandable thereby completing said fluid flow path and accomplishing an ability to control intermittent and/or continuous movement of moving devices.
