Abstract: To allow movement of a tilting cab on the suspension when travelling hydraulic fluid can flow through pipes (74 and 78) as the piston (76) moves to and fro in the tilt cylinder (18). When pressure is applied by pump (P) to the push chamber (48) by way of path (28) through one-way valve (46) to tilt the cab, the pressure on the pilot piston (50) holds it down against the spring (86) and closes the connection between pipes (74 and 78) through the annulus (68). When pressure is applied through path (30) to pull chamber (102) the piston (50) is lifted and holds valve (46) open for the return flow to reservoir (32). After piston (76) has passed pipe (74) the cab can fall freely to the rest position without further pumping.
