Filed: 1971-04-19
Abstract: 1324138 Valves BERGWERKSVERBAND GmbH 19 April 1971 [24 March 1970] 24343/71 Heading F2V A distributer valve, particularly for controlling the movement of an advancing pit prop system, has a pressure supply port 43, an exhaust port 74, and a port 59 leading to the pit prop, valve members 11, 12 engageable by piston rods operated by annular pistons 19, 20, 21, 22 in tubular chambers 23, 24, 25, 26, a central chamber 35 connected by a bore 56 to atmosphere, a first passage 45 connecting one or more of the tubular chambers to the pressure supply port 43, a second passage 61 connecting one or more of the tubular chambers to the port 59 leading to the pit prop, and a third passage 72 connecting one or more of the tubular chambers to the bore 56, each piston having the same diameter and the same effective area as the cross-sectional area of the piston rods and the surface area of the valve members delimited by their seats. The supply pressure from the port 43 acts through the passage 45 on the pistons 20, 22 so that only the force of a spring 28 opposes the opening of the valve 12 by a fluid-actuated piston 10. Pressure from the port 59 is similarly applied to pistons 21, 19 so that opening of the valve 11 by a second fluid actuated piston 9 is opposed solely by a second spring 27. The bore 56 collects leakage from the system in addition to providing a connection to atmosphere for some of the tubular chambers. A further passage 76 may be connected to measuring instruments. In an alternative construction, the chambers are formed by annular inserts and interchangeable plugs (such as 79, 82, Fig. 2) allow the valve to be connected with a high or low-pressure supply. Plungers (88) permit hand operation of the pistons (9, 10) and rotatable cores (92) permit selective interconnection with other valves in a series. In a further construction, the piston rods projecting into the chamber 35 are rigidly coupled and only one actuator for the valves is provided.

Patent GB-1277992-A (GB)
Title: Brake or clutch retractor assembly
Inventor: PLAAT C L
IPC: F16D65/54
Filed: 1970-05-21
Abstract: 1277992 Disc-brake actuators; friction clutches; slack-adjusters B F GOODRICH CO 21 May 1970 [21 May 1969] 24724/70 Headings F2C and F2E A brake or clutch retractor assembly (brake only shown), comprises a housing 19 secured in a torque frame 11, a retractor rod 35 attached to at least one brake member 12 and supported in the housing, a spring 23 connected to the housing and the rod for permitting the rod to move with the brake member upon actuation (see below) and then retracting it upon brake release, automatic adjustment mechanism for increasing the effective length of the rod 35 to accommodate wear in the brake, a locking plate 37 for holding the rod in the extended condition and a spring 45 for returning the rod to its original effective length on release of the locking plate 37. Both halves of Fig. 1 show the brake in released position, the upper half showing the situation when wear has occurred. When the brake is actuated by application of hydraulic pressure to piston 15, lining carrier 12 pulls with it rod 35. A locking plate 37, in the normally skew position shown, frictionally engages rod 35, and plate 37 also hooks at the top over a flange 34 of a sleeve member 22. Thus rod 35 pulls sleeve member 22 in its turn; a retaining ring 27 on sleeve member 22 compresses retractor spring 23 through washer 24. The normal brake clearance is the distance x between ear 42 on plate 37 and flange 43 on housing 19, and as long as this distance is not exceeded, rod 35 and sleeve member 22 occupy the same positions relative to each other. (The screwdriver 53 is normally absent). When wear occurs, ear 42 contacts flange 43 during brake application, thereby changing plate 37 to an attitude perpendicular to, instead of skew to, rod 35. Rod 35 is thereupon pulled further through sleeve member 22 by lining carrier 12 against the pressure of a spring 45. On release, the skew attitude of plate 37 is resumed, and rod 35 remains in its new position relative to sleeve member 22. " Rod " 35 as shown is hollow. The rod may be re-set to its original position by inserting screwdriver 53 in an opening 44 of housing 19 and " straightening " the locking plate 37, whereupon spring 45 draws rod 35 to the left. Another lining carrier 12 and retractor assembly may be mounted on the torque frame 11 on the other side of rotatable disc 13.
