Q1: What is the primary function and operating principle of the piston and cylinder block assembly within the FR hydraulic pump parts?
A1: The piston and cylinder block assembly is a core set of FR hydraulic pump parts responsible for creating the pumping action. In the bent-axis design, the precision-matched pistons reciprocate within the cylinder bores as the unit rotates, drawing in and expelling fluid. Their precise matching is critical for ensuring minimal internal leakage and smooth operation, directly contributing to the pump's high volumetric efficiency.
