Which option is not a typical hydraulic piston motor type?

• A. Bent Axis
• B. Radial
• C. Inline
• D. Spring Loaded

Answer: (D)

Hydraulic piston motors are categorized by how the pistons and their housing are arranged to turn hydraulic energy into rotation. The common configurations are Bent Axis, where the cylinder block is angled relative to the output shaft and a swashplate converts piston movement into rotation; Radial, where pistons are arranged around the shaft like spokes and drive the shaft as pressure acts on them; and Inline, where pistons are aligned in a straight line along the cylinder block for a straightforward, compact design. Spring loaded isn’t a standard motor type because springs don’t define how the fluid pressure moves the pistons to produce continuous torque. They’re typically used for return or biasing in other mechanisms, not as the primary means of generating rotational motion in a hydraulic piston motor. So the spring-loaded option isn’t considered a typical hydraulic piston motor configuration, unlike the Bent Axis, Radial, and Inline types.
