Abstract

PURPOSE: To aiming at reducing the cost of a variable pitch blade type pump, by incorporating a pressure distributing valve operated by a motor, in a controller so as to make the controller compact, and by eliminating a return lever and a starter which are conventionally used.
CONSTITUTION: A pressure distributing valve 12 which is incorporated in a blade angle controller and operationally engaged with a motor 16, consists of a spool chamber 12a and a spool 12b slid in the spool chamber 12a which communicates with a hydraulic pressure source 13 and a reservoir 14, and also communicates with upper and lower hydraulic chambers of a hydraulic servo valve (not shown) through a pipes 15a, 15b, respectively. Since the pressure distributing valve 12 operated by the motor 16 is incorporated in the controller as explained above, the controller can be made compact as a whole, and since a return lever and a starter conventionally used can be eliminated, the cost of the variable pitch blade type pump can be greatly reduced.
