I am by no means an expert on fluid dynamics and pump design so I do have a question about this design. Wouldn't an under square piston configuration with a 3" stroke require pivoting on each individual pump case to reduce side loading on the piston? Would an over square pump with a large bore...
This system is commonly known as a 'variable displacement hydrostatic transmission'. Mitsubishi Heavy Industries has invested somewhat in the idea with the purchase of Scotland-based Artemis Intelligent Power. Their design is also a radial piston pump with piston shut-off for low speed to...
