The tool part is mounted on the other press part 16 and the attachment is operated by movement of the press parts toward each other, the pressure generated in the pressure chamber 13 being transmitted via the diaphragm and blank to the punch 23 and blank holder 29 and in turn to chambers 41 and 42. The areas of the punch 23, the blank holder 29 and their respective plungers being such that fluid flows from one chamber 41 or 42, to the other, 42, or 41, causing the punch and tool parts to move in opposite directions. In the embodiment shown in Fig. 1 the punch is caused to move into the pressure chamber 13 while the tool ring descends. In an alternative form, Fig. 2 (not shown), the punch is made of larger area than the blank holding ring and descends into the ring so that the blank is formed in a cavity formed by the punch and the ring. The rate of forming is controlled by the rate at which fluid is allowed to escape from the chamber 31 formed on the side of the plunger 21 opposite chamber 41. Devices 56, and 60 detect the completion of a press stroke and the resetting of the attachment to its start position respectively. A device 51 acts on a stem 50 attached to plunger 21 to monitor the rate at which the blank is formed and is linked with a pressure control monitor 52 to control the rate of loss of fluid from chamber 31. Alternative constructions of the apparatus are given, Figs. 3 to 6 (not shown), in one the fluid chambers 41 and 42 are not concentric as in Fig. 1 but placed one above the other and in another one or both of chambers 41, and 42 may be replaced by a number of smaller chambers each having an individual plunger. The rate of forming is then controlled by increasing or decreasing the number of chambers used to operate either the punch 23 or the blank holding ring 29.

Title: A vehicle suspension unit with automatic level control
Inventor: LANGEN VIKTOR
IPC: B60G17/027
Filed: 1969-12-15
Abstract: 1298478 Vehicle suspension units VLANGEN [trading as LANGEN & CO] 15 Dec 1969 [15 Jan 1969] 61001/69 Heading F2S In a vehicle suspension unit consisting of a piston-cylinder assembly 7, 8 in series with a spring 2, self-levelling action is controlled by a valve which selectively connects fluid 10 in the cylinder to a high-pressure inlet P or lowpressure outlet T. The valve consists of a plunger 11 located in a bore in the piston 8 and loaded at opposite ends by springs 9, 13. The valve plunger is thus urged upwardly by the spring 9 plus the pressure of the fluid 10 and downwardly by the spring 13 plus the lower pressure in the space 30 above the plunger. Increasing cylinder pressure tends to expand the unit, but before any appreciable expansion occurs the valve plunger moves upwardly to open an inlet path 15, 16, 17, 19, 20, 21 to increase the quantity of fluid 10 and thereby lower the cylinder 7 with respect to the piston 8 and hence relieve the piston of part of the force previously exerted by the spring 9. The valve plunger will then descend and return to the stable state shown. Reducing cylinder pressure has a like effect, involving flow of fluid by way of 21, 20, 25, 22 to the exhaust T. The setting of the levelling valve is adjustable by means of a screw collar 13. Preferably the relationship C 2 /C 3 =f/(F-f) should be satisfied, where C 2  and C 3  are the rates of springs 9 and 2, respectively, and F and f the effective areas of the piston 7 and plunger 11. Check valves 16 and 24 prevent the unit from collapsing when the associated vehicle is not in use. The outlet check valve 24 is controlled by a pilot piston 23 acted on by fluid in a space 33 in communication with the space 30. The latter also communicates by a duct 31 with the levelling valve's outlet port 25. The action of the levelling system is damped by throttled flow of fluid (a) between the periphery of the enlarged head 28 of the valve plunger and the wall of the chamber 30 and (b) through a constriction 32 in the duct 31.
