Abstract

The circuit for regulating the temperature of a working fluid relates to machines which use a hydrostatic drive. A thermostat is fitted into the system for regulating the temperature of the working fluid. The thermostat automatically closes or opens the branch to the cooler as a function of the temperature of the reversible working fluid in the system. The heated reversible working fluid flows out of the thermostat directly in front of the filter into the suction branch of the filling-fluid pump, i.e. while avoiding the cooler and the tank. The thermostat thus closes the through-flow of the working fluid into the part of the circuit which contains the cooler and the tank when the working fluid is at a low temperature. When the working fluid reaches the temperature at which the thermostat opens, a portion of the working fluid flows through the connecting branch into the cooler and further into the tank. The thermostat opens fully when the temperature of the working fluid in the tank reaches the optimum value. All the working fluid which returns from the closed circuit flows further only via the cooler into the tank. <IMAGE>
