Abstract

558,824. Springs. SEAMARK, L. M. C. Aug. 25, 1942, No. 11953. [Class 108 (iii)] [Also in Group XXIX] A rotary valve comprises a longitudinally slotted tubular sleeve a with the opposite faces of the slot formed with complementary grooves to provide a cavity to recieve a spring device for expanding the sleeve, means being provided for compressing the spring device during the first part of the actuating movement to facilitate the rotation of the valve. In the form shown in Fig. 1, the upper end of the sleeve a is formed with a pair of projections b, c the projection b being divided by the slot off which continues to the lower end of the sleeve. The spring device, which engages part cylindrical grooves in the opposed faces of the slot, comprises a forked pin d having at a point somewhat below its middle a boss e of substantially circular shape in transverse cross-section. In the form shown in Fig. 8 the spring pin is difurcated at both ends and the upper arms are formed with recesses d<SP>2</SP> to facilitate its removal from the sleeve. The actuating spindle f is provided with a heavy flange f<SP>1</SP> provided with recesses to co-operate with the projections. On rotating the spindle one face of the recess co-operating with the projection b engages one face of the projection at the end of one of the short pins mounted in holes e<SP>1</SP> to compress the spring device and release the sleeve, which is then easily rotatable by the engagement of one face of the other recess with the projection c. The upper face of the flange f<SP>1</SP> has a groove with an outer vertical face and an inner inclined face adapted to receive a packing ring f<SP>6</SP> of similar shape. Springs i housed in recesses <SP>2</SP> in the sleeve press the sleeve and flange apart. A pin f<SP>3</SP> is screwed into a detachable cover g co-operates with an arcuate groove in the flange to limit the rotation of the spindle. The ports in the cylindrical cavity in the casing may be elongated to match the ports x on the sleeve and the passages leading from these ports may gradually merge into circular ports on the flanges. The line joining the casing ports may be offset from the axis of the sleeve.
