The invention relates to a nozzle element (2) the nozzle needle (6) of which opens into the interior and has a dead stroke (hT).
Actuator (V) for opening an aircraft nacelle cowl (7), comprising a dead travel device (19), characterized in that it comprises means (42a, 42b, 43) for blocking the dead travel device (19) when this actuator (V) is extended.
The invention thus represents an elegant process, suitable for automatic control, for the assembly of a tandem master cylinder and a vacuum-brake power-assistance servo and for simultaneously reducing the dead travel of the central valve (14).
A damping mechanism for a lost motion hydraulic actuator utilizes a thin edge orifice (66) in cooperation with a communication passageway (62) between the upper (46) and lower (48) chambers and controls the damping of the upper piston (38) on closure.
The drive of the other flap (10) has lost motion.
In this context, idle travel (8) is provided for the friction brake, with the result that at first only the eddy current brake engages, and after the idle travel (8) has occurred the friction brake engages.
A lost motion linkage (126) protects the actuator (106) from snatch loads.
The slides have preloaded bearings (28c) to allow a linear movement of each upright with no lost motion.
A lost motion float is used to reduce the loading on the connection bolts of the system.
The amount of lost-motion establishes the actual opening and closing phase angles for the valves.
A limited lost motion connection (143, 144, 145, 146, 147, 148, 150) is located between the turbine blade (114) and the counterweight assembly (120).
To achieve variable event timing, a lost motion coupling (10, 20, 14) is arranged between the drive wheel (10) and the camshaft (16).
The lost motion clutch mechanism (72a, 78e) includes a floating sector gear (72) driven by the gear train (64, 66, 68).
A lost motion clutch mechanism (72a, 78e) is provided between the gear train (64, 66, 68) and the output arm (42).
The backlash acceleration correction is initiated at the time of reversing of the sign of a positional deviation and is thereafter executed periodically.
The amount of lost-motion of each actuator is established by the timing of the opening and closing of the corresponding solenoid valve.
A servo motor control method which enables optimum backlash acceleration correction to be made automatically under various operating conditions of a machine.
The invention mainly concerns a method for making a master cylinder, in particular a tandem master cylinder comprising a step which consists in adjusting lost travel and a master cylinder obtained by said method.
A pair of driving faces (72a) of the sector gear (72) are interposed between a pair of driven faces (78e) on the carriage (78) in a manner providing lost motion between the sector gear (72) and the carriage (78).
A system for accomplishing solenoid control of engine valves places a solenoid valve between an oil gallery and the lost-motion actuator for each valve.
Although the basic phasing for the valves is established by a camshaft, the actual phasing is accomplished by causing the valve actuators to execute lost-motion.
A lost motion connection between the belt reel and the latch means permits limited belt movement by the user while maintaining the reduced tension until a predetermined retraction occurs.
An selectively-contractible wire is connected to the pawl by a lost motion connection and is operable to move the pawl to the release position when contracted to actuate the latch.
