Abstract
A hydraulic fluid distribution system includes a mechanical switch including a first valve, a first actuation pin extending axially from the first valve, and a second actuation pin extending axially from the first valve. The first valve includes an inlet port, a first outlet port, and a second outlet port. The first valve has a first position with the inlet port in fluid communication with the first outlet port and a second position with the inlet port in fluid communication with the second outlet port. The first actuation pin is configured to move in a first axial direction to transition the first valve from the second position to the first position, and the second actuation pin is configured to move in a second axial direction to transition the first valve from the first position to the second position. In addition, the hydraulic fluid distribution system includes a second valve having a first position that allows fluid communication between the first outlet port of the first valve and a first chamber and a second position that allows fluid communication between the second outlet port of the first valve and a second chamber. The second chamber is in fluid communication with a hyd…
