Car engine displacement pump volume controller comprises temperature- and pressure-dependent adjuster with return springs and piston and slide so pump volume responds to medium viscosity and temperature.

摘要

The adjuster (2) responds to a pressure-dependent element (5) as operably linked to a temperature-dependent adjuster (4) or electrical adjuster. The adjuster (5) has a return spring (11) whose coaxial adjuster element (12) is in turn operably joined to an adapter element (10) linked through to the main adjuster (2). Adjuster (12) connects pressure-free and pressurised housings (60,61) so the adjuster (12) responds to pressure gradient and spring (11) tension. Adjuster (12) connects to the temperature-dependent element (4) through element (13) and a slide (21) and its return spring (23).
