Title: Hydraulic, pneumatic and internal combustion engines. Hydraulic elevators
Inventor: SCHMOLS KARLHEINZ
IPC: F01B9/04
Filed: 1987-06-06
Abstract: The ends of the rocker beams can be provided at both ends with an extension, and these are held horizontal at all times by special devices. On these extensions, the ascending wells are transported under program control to the points which make possible the maximum utilisation of the nonequilibrium thereby achievable. The horizontal alignment of the extensions is brought about by motor-driven joints, pressure or vacuum devices which are mounted at the pivot joint between the rocker beams and the extension. In the event of usable pressure differences, the pressure or vacuum quantities required for this purpose are used by interposed paired-plate or disc-assembly machines. The supply of pressure or vacuum to these pressure or vacuum devices makes them reservoirs for this period. The forces are not lost because evaluation and use by paired-flap machines takes place subsequently. The pressure chambers of the pressure or vacuum alignment devices can also be used as reservoirs and taken out of the devices for subsequent output of the forces. Elastic, flexible disc assemblies can replace the pairs of flaps. Provided between the individual discs in the disc assembly are sliding means, balls with holding pockets and holding nets and spacers which transmit compression and tension.
