Abstract (en)
[origin: EP0238782A2] The control element of the 5/3-way valve unit is formed by two control slides which are arranged separately in the housing, in each case have two axially offset control edges interacting with two medium connections each and can be acted upon separately by control pressure. The control edges of the first control slide control the supply air of the first and the exhaust air of the second cylinder side; the control edges of the second control slide control the supply air of the second and the exhaust air of the first cylinder side. At control pressures below the pressure level required to overcome a restoring force acting on them, both control slides are located in their zero position blocking all medium connections, in which arrangement a very small dead space occurs for the control pressure, which ensures a high response speed of the control system in particular in the area of the zero passage with at the same time a very compact construction of the valve unit. <IMAGE>
