Abstract

1479494 Valves A H ANDERSSON & CO AB 4 Feb 1975 [28 Feb 1974 (2)] 4716/75 Heading F2V In a flow control valve having a housing 32 with an axial inlet 31 and a radial outlet 44, and a conical valve member 34 co-operating with a conical seat 33, an annular chamber 40 is formed downstream of the seat to avoid a subpressure zone being formed. As shown annular grooves 42, 41 form the chamber but the groove 41 may be replaced by a similar surface on the valve member. The conical valve member and seat surfaces may be curved. The valve member is shown screw-operated but a flow-regulating valve with a cup-shaped closure member (118) spring biased to an open position is described, Fig. 5 (not shown).
