Operation for lid of open top vehicle and of lid of storage space

摘要

The operation of the hydraulic cylinders is controlled by a valve system (12) which connects a common connection (D.H2) alternately between the pressure side (13) of a pump (10) and a reservoir (11). The common point (D.H2) is connected to work spaces (4,8) at the piston sides of the lid operating and locking cylinders (2,3) and the work spaces (7) at the sides of the piston rods of the top operating cylinders (1). Alternatively the connection is to the work spaces (6) at the piston sides of the roof operating cylinder (1). A common connection (P) connects to the pressure side (13) of the pump (10) and the operating spaces (5,9) at the piston rod side of the lid operating cylinder (2) and the lid locking cylinder (3).
