Abstract
A preferred constant horsepower, variable volume hydraulic pump (10) includes a wobble plate (22) coupled with interior end of the pump drive shaft (18) configured for sequentially stroking a plurality of pistons (28,30) received in respective cylinders (42,44) included as part of a nonrotatable barrel (24). A shifting mechanism (74) axially shifts the barrel (24) in accordance with the output pressure in order to change the stroke length of the pistons (28,30) in the cylinders (42,44) and thereby change the flow rate through the pump (10). The shifting mechanism (74) is configured to lower the flow rate as the output pressure increases in order to maintain a constant horsepower demand for maximizing the flow volume for a given horsepower.
