Title: Valve for controlling fluids
Inventor: STOECKLEIN WOLFGANG
IPC: F02M45/04
Filed: 2000-09-09
Abstract: The invention relates to a valve (1) for controlling fluids comprising a piezoelectric unit (3) for actuating a valve member (2) which can be axially displaced and inserted into a bore (8) of a valve body (9) and is provided with a valve closing member (13) at one end which cooperates with at least one seat (14, 15) disposed on a valve body (9) in order to open and close a valve (1). The valve closing member (13) separates a low pressure region (16) having a system pressure (p_sys) from a high pressure region (17). A filling device (26) is provided in the shape of a channel (27) with a throttling bore (28) in order to compensate for a leaked volume from the low pressure region (16) caused by drawing off hydraulic liquid from the high pressure region (17). The diameter thereof is selected in such a manner that a fluid volume flowing past said throttle bore (28) and emanating from the high pressure region (17) compensates for the leaked amount from the low pressure region when a defined minimum high pressure (p_R_min) prevails.

Title: Loom having cam driven reed - mounted on pivoting arms eccentrics to adjust pivot position
Inventor: FREISLER ERHARD
IPC: D03D49/60
Filed: 1972-09-21
Abstract: A loom has a reed carried on support arms extending radially from a rotatable support shaft, and pairs of angularly spaced radial arms on the support shaft carry rollers which follow respective rotating cams to effect angular oscillation of the support shaft and a beating up movement of the reed. The axle of the support shaft is rotatable in an eccentric base in a second shaft which itself is rotatable in an eccentric base of a third shaft rotatably supported in bearings in the loom frame. Rotation of the second and third shafts allows accurate adjustment of the rotational axis of the support shaft to ensure correct co-operation between the rollers and the cams, thereby providing improved beating up and a better quality weave. Pref. means are provided to manually rotate the second and third shafts, and the third shaft has a radially extending slot across which a locking bolt extends transversely whereby when the locking nut is tightened it deforms the third roller sufficiently to lock the second and third rollers in their set positions.
