<p>The invention relates to a hydraulic valve having a housing (2, 2', 2'') in which a housing partition formed with at least one passage (7) therethrough is provided between an inlet bore (3) and an outlet bore (4) aligned therewith, said passage having associated therewith a valve seat for a non-return valve element (9) adapted to close in one flow direction, said housing containing at least one flow channel (11) bypassing said passage for performing at least one further valve function. Known hydraulic valves of this type are either of excessive dimensions transversely of the flow direction and composed of several parts, or are of excessive length in the flow direction. According to the invention there is provided a compact hydraulic valve of inexpensive construction and composed of a reduced number of parts, such valve being characterized in that said flow channel (11) for said further valve function is formed in said housing partition together with said passage (7) and substantially within the cross-sectional area (Q) of said housing defined by the aligned bores (3, 4).</p> |
