ABSTRACT:
A multi-piston motor pump for the transfer of hydraulic energy from one hydraulic system to another without the transfer of fluid therebetween. A plurality of pistons are maintained in predetermined phase by a nutator mechanism or spider which is then used to rotate a shaft connected to valving means for the pistons which controls fluid to, or away from the pistons in a predetermined manner. The motor pump unit, in large measure, is made possible by improved couplings between the spider and the pistons that provide complete motion freedom, yet maintain definite position between the pistons and the spider. In addition, a rotary valve arrangement is disclosed which reduces the start-up friction loads of the unit to a minimum while being relatively reliable and easy to mechanize.
