摘要： A hydraulically actuated liftable and lowerable hook of a crane has a hydraulic system comprises at least one working machine with a hydraulic motor driving a winch. At least one drive machine comprising a pump is connected directly or indirectly to at least one of the working machines by means of two connections via corresponding working lines, which serve as a feed or return depending on the operating state of the working machine. A lowering brake valve is provided in one working line and is connected to the other working line via a control line such that the lowering brake valve is displaceable against a restoring force by pressure, which prevails in the other working line and is forwarded via the control line, from the blocking position of said valve into a through-flow position for lowering the hook by means of a primary winch.

摘要： A fluidically actuatable disk brake system includes brake cylinder pairs each including brake cylinders arranged on both sides of a brake disk in at least one brake caliper. Each brake cylinder includes a brake piston and a spring arrangement which applies a spring force toward the brake disk. First and second fluid connections are provided on the brake cylinder. The first and second fluid connections supply a fluid to the brake cylinder so that a force counteracting the spring force is applied to the brake piston. A 2/2-way valve is assigned either to the first or second fluid connection of first brake cylinders of a brake cylinder pair. The first or second fluid connection which is not assigned to the 2/2-way valve is fluidically connected to the respective other first or second fluid connection of a second brake cylinder of the brake cylinder pair.

摘要： A hydraulic disc brake master cylinder having a bar clamp attached to a master cylinder housing allowing the attachment of the master cylinder to a handle bar along a longitudinal clamp axis. The master cylinder also includes a cylinder wall associated with the master cylinder housing extending axially along the cylinder axis. The cylinder axis is not parallel to the longitudinal clamp axis. This embodiment further includes a reservoir for hydraulic fluid which includes a first wall which first wall includes only a radial portion of the cylinder exterior. The reservoir also includes an elastomeric diaphragm. The cylinder axis and the longitudinal clamp axis lie in a plane substantially bisecting the first wall. Thus, the symmetric master cylinder lever may be disposed on either the right or left portion of a handle bar without effecting operation of the master cylinder lever by a user.
