Patent GB-2072806-A (GB)
Title: A flow regulating valve
IPC: G05D7/01
Filed: 1981-03-26
Abstract: The flow regulating valve has a control slide (15) made substantially cup-like, sliding in a housing bore (11) and engaging by way of an end edge (16) of its opening a supporting member (13) under the force of a control spring (18). In this position, its inner chamber and the spring chamber are unloaded. Pressure medium delivered by a pressure medium source first of all influences only an annular area (24) at the open end of the control slide. As soon as the control slide is displaced by the pressure medium flow becoming greater, its inner chamber is also influenced and then the control slide regulates the flow of pressure medium to the load ports 31, 35. In this manner, the so-called initial jump, that is an excessively large flow of pressure medium at the start of the control operation, is prevented. In a modification the control slide 15 slides within a main spool valve closure member. <IMAGE>
