Title: Relief Valve Construction
Inventor: VANDERLAAN ROBERT DALE
IPC: F16K17/04
Filed: 1967-10-10
Abstract: 1,176,505. Valves. PNEUMODYNAMICS CORP. 10 Oct., 1967 [14 Dec., 1966], No. 46193/67. Heading F2V. A pressure relief valve comprises a differential-area plunger 37 biased by spring 27 to the closed position shown in which grooves 42 in the plunger are disposed to the right of sealing ring 41 and land 43 lies within a bore at the end of sleeve 19. Inlet pressure at 13 exerts a leftward force on the plunger and the latter moves at a predetermined pressure to connect port 13 to port 15 via grooves 42 and a metering zone defined by the right-hand end of land 43 and the left-hand end of sleeve 19. This zone has a greater restrictive effect than grooves 42 to protect ring 41 from erosive damage. The escaping fluid exerts a force on land 43 to compensate for the additional force imposed by the spring. The plunger may alternatively be moved by fluid pressure admitted to ports 15, 16 and acting on piston 44 and the plunger 37. The grooves 42 and ring 41 may be interchanged.

An impregnated sealing element is produced by immersing an element made of foamed material in a liquid consisting of or comprising an impregnation material e.g. a bitumen solution, and then rotating the impregnated element to remove excess liquid. Rotation may be about a horizontal, vertical or inclined axis, which may itself be moving e.g. to establish a cycloidal movement. Excess liquid removed by the rotation may be recycled and used in the impregnation step. The composition of the liquid used in the impregnation step is maintained constant.

Each further hydrofoil 11 is connected to a connecting member 17 of a piston-rod having a piston 18 located in a fluid filled cylinder in a rigid support member 10 depending from the vehicle structure 3, the piston being slightly smaller than the cylinder to restrict fluid flow therebetween and the damp motion of the connecting member 17 (and hence elements 21 and wall portions associated therewith), the motion being caused by the hydrofoil following the "profile" of waves. The connecting member 17 is pivoted to two elements 21 (only one is shown in Fig. 5) so that motion of the blocks pivoted at both ends of an element causes the element to rock. The stabilizing hydrofoils 1, 2, 6 are similarly mounted, but pivoted to only one element. In addition the trim of the vehicle may be adjusted by using the piston/cylinder of each stabilizing hydrofoil as an hydraulic actuator to raise or lower the stabilizing hydrofoils. Each side wall has wall portions 22 which are formed as bellows inflated to a pressure higher than that of the cushion 13 of the machine. The support members are surrounded by similarly inflated bellows 28 (not shown in Figs. 1, 3), and folded sheets 29 fixed between the bellows 22, 28 seal the wall of the cushion. The bellows 22 may be replaced by cloth wall portions (30), Fig. 8 (not shown), having horizontal reinforcing strips, or by a fabric covered with and sealed on to a flexible diaphragm (33), Fig. 9 (not shown).

A multiple feed knitting machine has pushers 6 with working legs 6a, 6b, 6c of different lengths and laterally bent lifting legs 7a in a rotating needle cylinder which form a constant or increasing width reinforcement in a ladies stocking, each pusher having a notch between the working and lifting legs on the side away from the needle cylinder the upper bearing surface of this notch cooperating temporarily with the lifting leg of an adjacent pusher to cause the various pushers to be selectably taken along during the reinforcement of the knitted work of variable width. When knitting takes place without reinforcing all the legs move in the path D 1  along the lower notch 13. The lifting cam 34 (Fig. 4) determines the beginning of the reinforcement at the knitting system I and this cam moves radially of the needle cylinder to act on the long legs 6a. The pushers 6 with long legs 6a are thus lifted to the path D 2  and the lifting legs 7a, 7b of end pushers in this group engage and lift the pushers with medium legs 6b 1 , 6b 2  to the path D 3  and the remainder again returned to the path D 3  by the cam 31. The number of medium-legged pushers increases on each rotation by two until the supply is exhausted thus producing a uniform widening of the reinforced part.
