Abstract: 1415838 Hydraulic reciprocating motors H ZADOW and H R J ZADOW 10 Nov 1972 [13 Nov 1971] 52797/71 Addition to 1307820 Heading F1A [Also in Division F2] In a valve assembly, Fig. 11, e.g. for controlling a double-acting piston 354, and comprising, as disclosed in Specification 1307820, a first valve with an inlet 356, at least one outlet 311 and a valve member 310 in the form of a plate to open and close the outlet, together with a second valve with an inlet 21 connected to the first valve outlet 311, an outlet 16, a further port 12 and a valve member 10 in the form of a plate movable to connect the further port 12 with the inlet 21 or with the outlet 16. The first valve plate 310 is positively moved in two opposed directions by an operating member such as a rod 307. In a modification, Figs.7 and 8 (not shown), the plate 310 is replaced by two plates with a spring between them. As shown, a third valve with a plate valve member 11 is connected to a second outlet 312 of the first valve, a rod 20 is arranged between the plates 10, 11 of the second and third valves, and the further ports 12, 13 are connected to the cylinder 350 on either side of the piston 354 and to further valve chambers 344, 344a containing plate valve members 345, 345a and connected also to drains 348, 348a and to passages 346, 346a leading to bores in which the opposed ends of the operating rod 307 move. In the position of the parts shown, fluid from inlet 356 passes to space 351a to move the piston to the left. When it reaches its end position, line 352 and 355a are de-pressurized to allow plate 345a to move and open passage 346a to drain 348a which causes the rod 307 to move under the influence of the inlet fluid-pressure so as to close outlet. 311 and open outlet 312. Thus plate 11 is moved to connect inlet 23 to space 351 and also to move plate 10 to connect space 351a through part 12 to outlet 16 and drain 357. As a consequence the movement of piston 354 is reversed. Such reversals of its movement continue but may be stopped by providing some over-riding control of one of the plates 345, 345a. Annular recesses 301a are provided around the outlets 16, 17 and the ends of bore containing the rod 20. The ends of the rod 307 may extend beyond the valve housing and be actuated mechanically or electromagnetically, or the rod 307, Fig.6, may be actuated by fluidpressure as described in connection with Fig. 11 but under the control of mechanically operated valves, e.g. 323 by which one or other of the passages 318 may be connected to a drain 327. The valves 323 may be actuated by further fluidcontrolled plates e.g. 332 or by diaphragms, e.g. 338. Fig.9 shows an arrangement in which the rod 307 is moved to the right when a fluid signal is applied to port 335 to open valve 323 but returns to the left when that signal is removed.
