A fluid delivery device includes a tube coupled to an axial manipulator. The axial manipulator includes an elongate member arranged to move axially in a housing. The tube is in fluid communication with a fluid diverter which is arranged to move axially in the housing upon axial movement of the elongate member. Seals are provided to prevent fluid from leaking out of the housing. A fluid port is in fluid communication with the tube via the fluid diverter, such that fluid can flow in and out of the tube via the fluid port and the fluid diverter.

[Object] To provide a compact, rationally designed, dual 4-port electromagnetic valve that is an electromagnetic valve having functions of two 4-port valves. [Solution] A dual 4-port electromagnetic valve includes two spools (8a, 8b) slidable independently of each other in a valve hole (7); two pilot valves (4a, 4b) that drive the two spools, respectively; a main supply port (P) that communicates with the valve hole (7) at a position where the two spools face each other; first and second output ports (A1, A2) that communicate with the valve hole (7) on two respective sides of the main supply port (P), first and second discharge ports (E1, E2) that communicate with the valve hole (7) on two respective outer sides of the output ports (A1, A2), third and fourth output ports (B1, B2) that communicate with the valve hole (7) on two respective outer sides of the discharge ports (E1, E2), and first and second supply ports (P1, P2) that communicate with the valve hole (7) on two respective outer sides of the output ports (B1, B2). The main supply port (P) and each of the first and second supply ports (P1, P2) communicate with each other.

A control device, in particular for hydraulically controlling components of mobile working machines, has a pressure supply connection (P) and a tank or return connection (T) in addition to two user connections (A, B). Control and/or regulating valves (10, 14, 16, 18) are connected between the individual connections (P, T, A, B). Two control lines (C, Z) can control at least one of the control and/or regulating valves. A modular-type functional block (24, 26) is connected to at least one of the control lines (C, Z).
