Abstract: A connecting apparatus connects to a main component (10) having a plurality of mutually adjacent fluid passage points (P?1, P?2, P?3, P?n . . . P?x). The connecting apparatus has a main body (12) controlling a fluid flow by a valve. A plurality of further fluid passage points (P1, P2, P3, Pn . . . Px) can be connected to each other in a fluid-conducting manner via the functional component (14) with assignable fluid passage points in the main component (10). One shut-off part, which shuts off the respective fluid passage point (P?2, P?3, P?n . . . P?x?1) in the main component (10) and/or in the fluid passage point remains unaffected by the functional component (14). In each case a fluid-conducting connection line (30, 32) is inside the main body (12) between the further fluid passage points (P1, P2, P3, Pn . . . Px) and the functional component (14) and can be shut off by a separate shut-off part, as long as the associated connection to the functional component (14) remains unused.

Abstract: A hydraulic valve device, in particular an LS directional valve, includes a housing (1), with a pressure supply connection (P), at least one utility connection (A, B), and a load-reporting connection, and includes a controller (5) moveable in two directions to at least partly actuate fluid those connections. An adjustable stop device (25, 31, 47, 59) restricts the stroke length of the travel movements of the controller (5) or parts of the stroke length in either direction. The stop device (25, 31, 47, 59) has a stop surface (25) facing in one movement direction and a second stop surface (47) facing in the other movement direction on the same axial end region (19) of a slider piston (5). A counter stop (31, 59) is provided for each stop surface (25, 47). Both counter stops are on the respective same housing end region (11) of the housing (1) in a positionally adjustable manner.

Abstract: The invention relates to a connecting apparatus, provided for fluid-conducting connection to at least one main component (10), which component has a plurality of mutually adjacent fluid passage points (P?1, P?2, P?3, P?n . . . P?x), said connecting apparatus having a main body (12), which serves to control a fluid flow by means of at least one functional component (14), such as a valve device; a plurality of further fluid passage points (P1, P2, P3, Pn . . . Px), which can be connected to each other in a fluid-conducting manner via the functional component (14) with assignable fluid passage points in the main component (10); and at least one shut-off part, which shuts off the respective fluid passage point (P?2, P?3, P?n . . . P?x?1 in the main component (10) and/or in the main body, said fluid passage point remaining unaffected by the functional component (14).

Abstract: The invention relates to a hydraulic valve device, in particular an LS directional valve, comprising fluid connections provided on a housing arrangement (1), such as at least one pressure supply connection (P), at least one utility connection (A, B), and preferably a load-reporting connection, and comprising a controller (5) which can be moved in one movement direction or another movement direction in order to at least partly actuate fluid connections of the housing arrangement (1). An adjustable stop device (25, 31, 47, 59) is provided which restricts the stroke length of the travel movements of the controller (5) or parts of the stroke length in the one direction or in the other direction.

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

Abstract: The invention relates to a first valve component (10), in particular a pressure compensator-type component, comprising a valve slide (16) that can be guided in a valve housing (12) in a longitudinal direction, said valve slide having a control part (34) for Controlling a fluid-conducting connection (28) between at least two fluid connection points (30, 32) accommodated in the valve housing (12). Said control part has at least one pocket-like recess (38), at least part of which is bordered by a fluid-guiding surface (40) running at least between two vertices of the recess and running with increasing inclination from one vertex to another vertex. The first valve component is characterised in that, starting from a predeterminable distance before the other vertex, the fluid-guiding surface (40) runs from its point of greatest inclination with decreasing inclination in the direction of said other vertex. The invention also relates to two further valve components.
