Title: Coalface conveyor incremental advance control - metering cylinder with equal spaces linked to face end controls
Inventor: JUNGMANN KURT
IPC: E21D23/00
Filed: 1973-07-17
Abstract: Incremental advance controls for a coalface conveyor operates a group of double-acting shifting cylinders connected to the console at the face end and an energy producer with interposed multiple valve together with pre-set non-return valves and metering cylinder in the tap lines for each shifting cylinder. A floating piston divides the metering cylinder into equal spaces which alternate as fill and expulsion spaces, each linked individually via a two-way face line to the multiple control valve at the console, via a non-return valve which closes on the console side. These two individual lines are linked at the console side of the valves by a line fitted with two non-return valves which close off the centre of the link line to return fluid to the front space of the respective cylinder. Each metering cylinder space is connected by an extension line to a link line joined to the rear space of the metering cylinder, with pre-set non-return valves in the space extension lines. Each non-return valve from one space of the cylinder is connected via a control line to the face line tap branch used to feed pressure medium to the other space of the particular metering cylinder, behind the non-return valves on the console side.
