Abstract
Abstract A valve block comprising a plurality of electromagnetic valves (2, 3) and a vlave cap (16) and including an electric power supply for applying electric power to the coils of the electromagnetic valves, and wherein a printed circuit board (14) is utilized. The printed circuit board is mountable as a component unit onto all contact points of the coils (6, 7, 8, 9) of the electromagnetic valves. The printed circuit board carries conductor tracks for electrically connecting coils ( 6, 7, 8, 9) to the outgoing cable of the valve block (1). The printed circuit board (14) exhibits a contact device (21) in which all tracks are terminated. Through the contact device (21), the electrical connection to the connecting cable (28) is established. Accordingly, a simplified assembly of the valve block is provided, and the valve block assembly is water-tight and sealed against the ingress of dirt and vapor into the engine space.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
A valve block assembly comprising, in combination: a housing enclosing a portion of said valve block assembly, one or more electromagnetically actuable hydraulic valves, a value cap, a power supply means for applying electric power to the coils of the electromagnetic valves through a plurality of electrical contact points, wherein a printed circuit board is provided which is mountable on all of said electrical contact points of the coils as one component unit, and including electrical tracks to establish electrical connections between the coils and an outgoing cable of the valve block, wherein the printed circuit board includes a contact means for an output cable common to all tracks, which contact means is configured so that a removable plug contact of the connecting cable is directly plugged over an edge portion of the printed circuit board forming part of the contact means and a projection of said housing extending away from said edge portion and generally parallel to said printed circuit board for receiving and supporting said plug contact.
Claim 2
Dependent Claim
169 words
A valve block assembly comprising, in combination: a housing enclosing a portion of said valve block assembly, one or more electromagnetically actuable hydraulic valves, a value cap, a power supply means for applying electric power to the coils of the electromagnetic valves through a plurality of electrical contact points, wherein a printed circuit board is provided which is mountable on all of said electrical contact points of the coils as one component unit, and including electrical tracks to establish electrical connections between the coils and an outgoing cable of the valve block, wherein the printed circuit board includes a contact means for an output cable common to all tracks, which contact means is configured so that a removable plug contact of the connecting cable is directly plugged over an edge portion of the printed circuit board forming part of the contact means and a projection of said housing extending away from said edge portion and generally parallel to said printed circuit board for receiving and supporting said plug contact.
Claim 3
Dependent Claim
42 words
A valve block assembly according to claim 1, wherein the printed circuit board is made of insulating material provided on which said tracks a provided, that the said tracks are disposed in guided-together manner in the contact means and exhibit contact points.
Claim 4
Dependent Claim
58 words
A valve block assembly according to claim 1, wherein a plug housing is provided for the connecting cable of the valve assembly, which plug housing comprises a resilient and sealing material on a cap projection, wherein said plug housing is provided with a plug pushable on a part of the printed circuit board configured as a plug assembly.
Claim 5
Dependent Claim
111 words
A valve block assembly according to claim 1, wherein a plug housing is provided for the outgoing cable of the valve assembly which comprises a flexible and sealing material, which can be pushed on a cap projection and which includes a contact element on a displaceable plug assembly held by a displaceable plug assembly-receiving slidingly guided in the cap projection formed as a guiding means, where in the plug assembly-receiving member is provided with a contact element which upon displacement of the plug housing and of member sweeps a marginal area of the printed circuit board provided with one or more ends of track, with an electrical contact thereby being established.
Claim 6
Dependent Claim
77 words
A valve block assembly according to claim 1 wherein the printed circuit board is furnished with pre-manufactured tracks and is arranged to be mountable during assembly onto pins of said coils in establishing electrical contacts, wherein all electrical contacts are subsequently soldered, wherein the cap, in surrounding the printed circuit board, is mountable on the valve block. and wherein the plug assembly of the printed circuit board is connected to the plug connector of the connecting cable.
