Abstract

1,125,127. Valves. ROBERT BOSCH G.m.b.H. 7 Oct., 1965 [9 Oct., 1964], No. 42517/65. Heading F2V. The spool 5 of a valve has pistons 6, 7 defining actuating chambers 9, 10 and a control chamber 8. Within the latter the spool carries a D- shaped valve 28 having a semi-cylindrical face engaging the wall of the bore 2. In the position shown, a pressure inlet 22 communicates via chamber 8 with a port 23 leading to one side of a motor 23<SP>1</SP>, whilst the other side of the latter communicates via port 25 and the valve 28 with an exhaust. On moving the spool to the left, valve 28 interconnects ports 23, 24 and port 25 is opened to chamber 8. A pin 35 engaging a recess 36 in the spool prevents rotation of the latter. The D-valve 28 may be loaded by a spring 27 and/or fluid pressure. In the embodiment of Fig. 3, not shown, the spool (48) carries two D-valves (49, 50) controlling the communication between an inlet (47), work ports (45, 46) and exhaust ports (43, 44). In Figs. 4 and 5 (not shown), the spool (57) carries two pairs of D-valves (59, 61) and (58, 60), each pair corresponding to the pair of Fig. 3. In Fig. 6, not shown, the D-valve (73) has a central partition (74) and controls the communication between an inlet (84), work ports (80, 83), and exhaust ports (81, 82), the latter containing a restriction (82<SP>1</SP>).
