Title: Rotary pump or motor
IPC: F01C21/08
Filed: 1962-02-28
Abstract: A rotary pump or motor of the outwardly sliding abutment type, described as a two-stage compressor, comprises a housing 11, Fig.1, formed by cylindrical parts 12, 13, end covers 15, 16 and a divider wall 14 to form cylindrical chambers 33, Fig. 2, through which passes a concentric shaft 17 driven by a pulley 83 to which is secured a cooling fan 85. On the shaft 17 are eccentrically mounted rotors 21, 22, one in each chamber, with their eccentricities 180 degrees with respect to each other. Each rotor is formed with lightening holes 52, and to reduce the off-centre weight of the rotors, an axially extending recess 38, housing a wiper bar 37, Fig. 3, urged by a leaf-spring 39 into sliding contact with the chamber wall 32 and on its end faces 44 with recesses mounting flexible seal rings 43 which are split to straddle the wiper bar. To provide a proper sliding fit for the bar 37, a resilient strip 40 and a metal strip 41 are fitted in the recess 38 at its leading edge. The outwardly sliding abutment comprises a blade 23 guided at its ends in grooves 26, 27 in an end cover and the divider wall and passing with clearance through a slot 35 into a cavity 34 to which pressure fluid at regulated pressure is supplied through a line 78. The pressure fluid acts on sealing plugs 54, 55 mounted in a bore 53 intersecting the slot 35 to urge the blade 23 into contact with its rotor. The plugs 54, 55 each have a flat surface, the one on the plug 54 being exposed to pressure on the high pressure side of the blade 23 and the one on the plug 55 to pressure in the cavity 34 so that the plug 54 is urged outwardly and the plug 55 inwardly. With the build-up in pressure on the high pressure side of the blade 23, the blade is urged outwardly against a spring-loaded plunger 65 just before the bar 37 passes the slot 35 to be free from contact from the bar to be again urged into contact with the rotor by the spring-loaded plunger 65, 72 immediately the bar passes the slot. An air cleaner 86 is fitted on the inlet connection 87 to the first stage, and an intercooler between the stages. Lubrication oil admitted to the chambers 33 through pipes 98 is afterwards separated from the compressed air. Lubricating oil for the bearings is admitted through pipes 99. In a modification, a rocker assembly 110, Fig. 11, having rollers 117 resiliently loaded by springs 113 co-ordinates the movements of the rotors of the two stages. The driving pulley 83 may be counterweighted to balance the off-centre load of the rotors.

Patent ES-347195-A1 (ES)
Title: Dual-network disk brake
IPC: F16D65/18
Filed: 1967-11-15
Abstract: An actuating cylinder for a dual-circuit braking system has a stepped piston 1 (Fig. 1) with a second pot-shaped piston 2 sliding on the stem of the first, the two pistons having the same external diameter, one pressure line 6 being connected between the second piston 2 and the casing 7, and the other pressure line 5 being connected via a double-acting valve 4 to the space between the two pistons. If the first line 6 fails, the piston 2 will be forced against the casing and the pressure in line 5 will move the inner valve member 17 to the right to close a bore 9 (Fig. 2). The whole valve member 11 then moves to the right against a spring 16a unseating the edge 11a so that fluid passes through longitudinal grooves 10 into the chamber 3 (Fig. 1) to displace the piston 1 to the left and apply the brakes. On release, fluid from chamber 3 returns partly by the same path and partly via longitudinal grooves 15 in the inner valve member 17 and in the valve stem 14. If there is no pressure in line 5, movement of piston 2 displaces the inner valve member 17 to the left against a spring 16 until it seats at 12. The chamber 3 is now sealed and both pistons move together. If the pressure in line 5 fails after application, the pressure in chamber 3 seats the inner valve member 17 as before. On release, the pressure in chamber 3 is relieved and the inner valve member 17 is unseated by the spring 16. The brake reservoir preferably contains an indicating device to show when the liquid level or pressure has fallen below a particular value. Modifications.-The spring 16 may be located at the end of the valve stem 4 (see 20 in Fig. 1). The inner valve member 17 may be without the longitudinal grooves 15, in which case pressure relief in chamber 3 occurs by displacement of this member towards the seal 12. The valve stem 14 may be a clearance fit instead of having longitudinal grooves.
