Abstract: The present disclosure relates to a brake fluid device comprising a brake fluid reservoir having a storage space, having a fastening device for fastening to a pressure generator unit of a motor vehicle brake system and/or to a mounting interface in a motor vehicle. The brake fluid interface has an outlet interface for transporting brake fluid into such a pressure generator unit, and having an inlet interface (15) for brake fluid. The brake fluid device further includes a filling adapter having a filling opening, having a receiving space, and having an outlet interface for brake fluid. A brake fluid line connects the outlet interface of the filling adapter and the inlet interface of the brake fluid reservoir and through which brake fluid is able to flow from the filling adapter into the brake fluid reservoir.

Abstract: A rotor blade assembly for a wind turbine is disclosed with a first blade segment having a female structural member defining an internal cavity, and a second blade segment connected to the first blade segment at a chord-wise extending joint. The second blade segment has a male structural member that is received within the internal cavity of the female structural member of the first blade segment. At least one floating connector, for joining the first and second blade segments, is positioned in at least one of a generally chord-wise direction and a generally span-wise direction. The floating connector has a biasing element configured to restrain bi-directional movement of a floating pin within the floating connector.

Abstract: A bicycle hydraulic operating device is provided with a cylinder including a cylinder bore, a first reservoir tank including a first reservoir opening, and a second reservoir tank including a second reservoir opening. The first reservoir tank is in fluid communication with the cylinder bore, and the second reservoir tank is in fluid communication with the cylinder bore.

Abstract: A master cylinder includes a cylinder bore, a first piston positioned within the cylinder bore, a second piston positioned within the bore and located forwardly of the first piston, a first pressure chamber within the cylinder bore and defined in part by a rear portion of the second piston and a forward portion of the first piston, a first pressure chamber seal extending radially outwardly from the rear portion of the second piston, a first reservoir inlet configured to provide fluid communication between a reservoir and the cylinder bore at a location forwardly of the first pressure chamber seal, and a first groove extending axially along the cylinder bore and positioned such that (i) when the second piston is in a released position, the first groove is located directly outwardly of the first pressure chamber seal and the reservoir is in fluid communication with the first pressure chamber through the first groove, and (ii) when the second piston is in an activated position, the first pressure chamber seal is

Abstract: The present invention provides an apparatus and method for filtering fluid in a breather assembly and providing uncontaminated fluid to a reservoir. The breather allows in-take fluid traveling through a first flow path to be filtered before entering the reservoir through a first directional valve. The breather also allows exhaust fluid traveling through a second flow path, separate from the first flow path, to exit through a second directional valve.

Abstract: A hydrostatic transmission assembly includes a first gerotor motor, a pump housing, a first variable displacement pump, a second gerotor motor, and a second variable displacement pump. The first gerotor motor includes a first output shaft aligned along a first axis. The pump housing connects to and contacts the first gerotor motor. The first variable displacement pump includes a first driven shaft mounted to the pump housing and aligned along a second axis, the second axis being generally perpendicular to the first axis (the first output shaft axis). The first variable displacement pump is in fluid communication with the first gerotor motor via passages in the pump housing. The second gerotor motor includes a second output shaft generally aligned along or generally parallel to the first axis. The second gerotor motor is connected to the pump housing on an opposite side of the pump housing as the first gerotor motor.

Abstract: A muscle activity monitoring system that integrates a minimal data-collection and analysis system into a disposable, single-use device that achieves data collection and analysis without requiring the assistance of a trained technician. The monitoring system includes a muscle activity sensor for sensing muscle activity at a location on the body, and a processor for analyzing the sensed muscle activity to determine a presence of a pattern of muscle activity that is correlated to a diagnosis. The diagnosis is displayed by a plurality of non-volatile markers. The markers are preferably heat-sensitive or electrochemical cells that undergo a permanent detectable change when a current flows through the cells. A housing houses the processor, the display, and a power source on the muscle activity sensor.

Abstract: A cylinder-piston unit including a central valve having a valve shaft, on which two spring plates with a pre-stressed restoring spring are disposed. One of the spring plates is engaged from behind by a cross-sectional enlargement of the valve shaft which has a valve closing element. The cross-sectional enlargement is formed by a collar of the valve shaft. Another cross-sectional enlargement comprises a sleeve, which is longitudinally displaceably guided on the valve shaft. On the side remote from the restoring spring, the sleeve has an enlarged inner bore, with which the enlarged inner bore complementarily fits over a snap ring that engages the valve shaft. As a result, a form-locking connection is attained between the sleeve and the valve shaft that assumes that a preassembled valve component unit will be held together even if the snap ring breaks.

Abstract: An arrangement for supplying pressurized fluid into a user circuit, particularly a master cylinder of a clutch, includes a cylinder housing defining a bore. A cylinder sleeve is slidably accommodated in the bore and bounds an external feeding compartment with the housing, as well as an internal pressure chamber. A piston is received in the pressure chamber for displacement in the axial direction of the arrangement in response to the application of an external force, especially that of a clutch pedal, thereto, to exert pressure on the fluid present in the pressure chamber. The sleeve has a connecting port at its end remote from the point of application of the external force, and the housing has an auxiliary port communicating with an auxiliary reservoir and a supply port which communicates with the user circuit.

Abstract: A position-transmitting equipment especially suitable for transmitting steering commands in a small watercraft comprises a transmitter unit in which a cylinder is reciprocable endwise in a housing in accordance with position information to be transmitted. The cylinder is divided internally into two working chambers by a transverse partition. A gland at each end of the cylinder seals about a tubular plunger fixed to the housing so that reciprocation of the cylinder differentially adjusts the working chamber volumes, without risk of jamming and the need for close tolerances. The housing, cylinder and plungers can all be made of plastics material. The plungers provide communication via conduits to a double-acting actuator constituting a receiver unit. The equipment optionally includes a recuperator unit to maintain a selected working fluid pressure in the system.
