Abstract
A hydraulic driver is provided for a loom shuttle. The driver has a hydraulic cylinder (12) with a working piston (59) shiftably disposed in the cylinder for emitting throwing energy direct to the shuttle. There is also a supply valve (11) connected to the hydraulic cylinder (12) and distributing hydraulic fluid from a pressure medium source to the hydraulic cylinder (12) by the intermediary of a pressure accumulator (9) mounted on this cylinder. The supply valve is controlled by a magnet valve (10) directly connected to one end of the supply valve.
Claims10
A hydraulic driver for a shuttle in a power loom, characterized by a single action type hydraulic cylinder (12) with a working piston (59) shiftable therein for emitting throwing energy direct to the shuttle (6), and a supply valve (11) connected to the hydraulic cylinder (12) and distributing hydraulic fluid from a pressure means source to the hydraulic cylinder (12) via a pressure accumulator (9) mounted on the hydraulic cylinder, said supply valve being controlled by a magnet valve (10) directly connected to one end of the supply valve, substantially all of the hydraulic fluid amount used for one stroke of the working piston being supplied by the pressure accumulator (9) which is then refilled from the pressure means source and the return stroke of the working piston (59) being produced by an exterior compressed air cylinder, the entire apparatus being produced as a compact unit mounted on the lathe (7) of the loom.
