DECKMASTER MCV 106AXXXX Hydraulic Displacement Control-PV BULLETIN 95-8972 APPLICATION The MCV106A Hydraulic Displacement Control (HDC) is a   cost-effective   hydraulic   pump   stroke   control   which uses    mechanical    feedback    to    establish    closed-loop control of the swashplate angle of Sundstrand Series 2X and Series 3X pumps. The HDC accepts a differential hydraulic pressure signal from   a   control   handle   or   servovalve   and   uses   the differential pressure to drive its double spool arrangement  and  port  oil  to  the  pump  servocylinders. The   spool   configuration   allows   a   null   deadband   for machine  safety  in  the  pump's  output  while  maintaining optimum dynamic response to control commands. FEATURES •   Servo   control   deadband   independent   of   signal   null deadband:  offers  safety  combined  with  accurate  and responsive control •   Resistant   to   the   environment:   shock,   vibration   and humidity tested • High porting spool force resists chip plugging •  Swashplate movement can be visually detected at the feedback shaft * Low cost SPECIFICATIONS HYDRAULIC OIL VISCOSITY 40-6000 SSU OIL TEMPERATURE -40°  to 121°  C (-40°  to 250°  F) operating range 21°  to 82°  C(70" to 180°  F) rated performance range- 2X Series 21°   to  104"  C  (70°   to   220°   F)   rated   performance range-3X Series MINIMUM SYSTEM FILTRATION 10 Microdh ENVIRONMENTAL SHOCK 50   g   for   11   milliseconds.      Three   shocks   in   both directions  of  the  three  mutually  perpendicular  axes for a total of 18 shocks. VIBRATION Withstands     a     vibration     test     designed     for     mobile equipment controls consisting of two parts: 1. Cycling from 5 to 2000 Hz in each of the three axes. 2. Resonance dwell for one million cycles for each resonance point in each of the three axes. Subject    to    acceleration    levels    of    1    g    to    46    g. Acceleration level varies with frequency.
