If the motor is single-acting the valve 37 is omitted and the valve 38 is spring loaded to its open position. To perform an extension stroke the distributer 14 is operated to direct fluid to the chamber 60, the valve 38 closes, and hydraulic fluid in the chamber 61 is expelled through bores 26, 28, 27 in the piston 21 to the line 15 connected directly (single-acting) or indirectly via distributer 14 (double-acting) to the main reservoir 18.
Patent ES-359452-A1 (ES)
Title: Device for delaying the opening of the pulse contact for telephone dials
IPC: H04M1/34
Filed: 1968-10-23
Abstract: Lost motion is provided in a telephone dial mechanism by rotating a member with the impulsing cam which member engages a part of the impulsing spring set until the latter is moved as a whole by the cam to release the member which rotates until it engages the spring set again when rotation of the cam causes the impulsing contacts to be operated. When the dial is set, cam B is driven anticlockwise and the lost motion member rotates with the cam until projection C engages contact operating arm E. On release, cam B and the member rotate clockwise until projection D engages short contact arm A and the member stops (Fig. 2). Further rotation of cam B pushes arm E downwards to push the closed contacts A out of engagement with projection D so the member rotates again until projection C engages long contact arm A. On further rotation of cam B, the contacts are pushed downwards so that projection C engages the short contact arm A and the contacts open as the cam rotates further. In a modification, Fig. 7, the first engagement is made by arm 3 on the lost motion member which engages extension 4 on operating arm 10 until it is disengaged by upward motion of the eccentrically mounted lost motion member which is then rotated to the position shown for impulses to be produced. Additional pauses in the pulse train are produced by cam 7, mounted on the dial shaft, which moves projection 2 away from contact spring 5.
