ABSTRACT:
An integrated drive generator for an aircraft and a method of making and operating the same result in improved operation of the integrated drive generator, especially during cold start-up. This is accomplished through the use of at least one stop to prevent each of the cylinder blocks in the hydraulic pump and motor assembly of the integrated drive generator from moving away from the port plate more than a predetermined amount which will ensure establishment of hydraulic continuity between the pump and motor without substantial delay during cold start-up of the integrated drive generator.
