Abstract: A control system for controlling the motion of a hydraulic elevator calculates a deceleration distance based upon the elevator velocity and begins the deceleration phase of the elevator motion upon the elevator reaching the calculated distance from the landing. In a particular embodiment, the control system includes a hydraulic valve (38), a space encoder (16), and a controller (42). The space encoder (16) produces velocity and position measurements. The controller (42) uses the velocity inputs to determine the deceleration distance and, upon the elevator car (14) reaching the calculated distance from the landing as measured by the position inputs from the space encoder (16), commands the hydraulic valve (38) to actuate and begin the deceleration phase. In an alternate embodiment, an interface unit (56) connected between the controller (43) and the hydraulic valve (38) calculates a delay between the deceleration command based upon a predetermined distance and the calculated deceleration distance based upon car velocity. Upon expiration of the delay, the interface unit (56) commands the hydraulic valve (38) to actuate and begins the deceleration phase.

Abstract: A transition valve for a hydraulic elevator includes a block, a spool, an actuator, and an end cap. The actuator may be either a solenoid type actuator or an electric motor type actuator. The end cap includes an opening permitting engagement between the actuator and the spool. In a particular embodiment, the actuator is an electric motor engaged with the spool via a crank and arm. This arrangement translates the rotational motion of the motor into linear motion of the spool with a sine curve profile.
