DE2224308A1 - COMPONENT COMPONENTS OF A PLATE-LIKE VALVE HOUSING WITH FOUR PRESSURE MEDIUM VALVES - Google Patents

Description

From a plate-like valve housing with four pressure medium valves existing component.

The invention relates to a plate-like valve housing with four pressure medium valves existing component that with the same components can be assembled and in which the center lines of the valves lie in one plane. The invention also relates to a method for producing such a component.

In hydraulic control and drive circuits, it is known to use valves to be assembled in blocks and to be switched on for various switching and control options and to lock. This assembly of valves in large numbers is complex and results in valve combinations, control stations and control rooms of large dimensions.

The invention is intended to show a way as with the simplest Means a switching station for pressure medium circuits can be built, the the number of valves to be used and their type of valve is practically unlimited.

This object is achieved according to the invention in that in one Component the center lines of the valves arranged in pairs at right angles to each other are and the openings for the inlet and for the outlet at the same time as through holes for the medium and as passage openings for tie rods for several components are trained.

Such a component is produced in a simple manner in that four holes are made in the plane of the center lines and a valve is inserted into the first and second bores at each end, a valve is inserted into the third hole at both ends and the fourth hole forms a connection for the first and second hole, and at right angles to the level of the third and fourth valve bore, these penetrating each one through bore is made.

Among other things, pressure valves, control valves, throttle valves, Check valves, flow control valves, pilot valves, brake valves, shuttle valves are inserted into the holes.

The simplicity of making the four valve bores in one Component results in a versatile application.

The invention is shown in one embodiment in the drawing and explained in detail in the following description.

The figures show: FIG. 1 a plan view of a component in the scheme, FIG. 2 several assembled components and FIG. 3 shows a section along line III-III of Fig. 1.

A plate-like valve housing lo receives a first bore 1 and a second hole 2, and in each of these two holes 1 and 2 a valve 5 and 6 inserted at one end. the other ends 7 and 8 are used as consumer connections. A third hole 3 takes on each of its two ends a valve 13 and 14, respectively. A fourth hole 4 connects the two holes 1 and 2.

In a perpendicular plane to the third and fourth bore -3 and 4 there is a through hole 11 and 12 for the pump connection and the tank connection. The bores 11 and 12 penetrate completely or partially through the third and fourth bores 3 and 4. They also serve to hold tie rods 9 for chaining or for joining several components lo.

According to the embodiment, the valves 13 and 14 can laterally of the connection 11 are arranged so that they connect without auxiliary bores to form connection 7 or 8.

The connection bores 7 and 8 are also the inlet bores to valves 5 and 6, which can be connected to port 12 in the return, the required bore 4 being closed by attached covers or valves can be. Any connections between the connections 11 according to FIG and 8 and 12 according to 7 and 8, respectively.

Several components 11 are linked in that tie rods 9 within the supply bores 11 and 12 connect them.

The tie rods 9 in the bores 11 and 12 leave enough cavities for the flow of the pressure medium. The attachment of the tie rods 9 to the outer Valve housing lo takes place with seals and screw connections in a known manner (Fig. 3).

Additional valve blocks can be placed on the outside of the components and control organs can be set optionally. When a valve opening in a component lo should not receive a valve, the opening is closed so that in more revealing Way hydraulic control and working circuits can be switched and optionally any number of valve housings 10 can be assembled.

It is also possible to use only three dohrings 1 to 3 in the plate-like To introduce valve housing 10 and to form a through hole 12 so that that it connects holes 1 and 2. The bore 4 can then be omitted. To achieve this goal, either the through hole 12 would have to be the holes Cut 1 and 2 or holes 1 and 2 cut through hole 12 undercuts are made or inserts are formed accordingly.
