Which type of hydraulic pump is known for having both increasing inlet and decreasing outlet chambers?

The axial piston pump is recognized for its unique design that incorporates both increasing inlet and decreasing outlet chambers. This type of pump employs a series of pistons arranged parallel to the axis of the cylinder. As the pistons move within their respective chambers, they create a vacuum at the inlet side, allowing fluid to be drawn in, thus increasing the volume in that chamber. Meanwhile, the fluid is expelled from the outlet chamber as the piston rotates and decreases the volume, hence the term "decreasing outlet."

This characteristic mechanism enables the axial piston pump to produce high pressure and flow rates, making it particularly efficient for applications requiring significant hydraulic power. The design can accommodate varying flow rates and is often used in mobile and industrial applications where precise control and high performance are necessary.
