Abstract
A hydraulic assembly has a first fluid valve and a second fluid valve. A switching valve having a first fluid input and a second fluid input also has a fluid output. The first fluid input is in fluid communication with the first fluid valve while the second fluid input is in fluid communication with the second fluid valve. The switching valve is configured to switch fluid communication to the fluid output between the first fluid input and the second fluid input. A fluid actuator is in fluid communication with the fluid output. A housing for the switching valve is provided. The housing has a first portion and a second portion. The first portion has a first fluid passage permitting fluid communication between the first fluid valve and the first fluid input and a second fluid passage permitting fluid communication between the second fluid valve and the second fluid input. The first fluid passage has a first opening and the second fluid passage has a second opening. The second portion has a first seal to seal the first opening and a second seal to seal the second opening.
