An example hydrostatic transmission includes (i) a motor section having a motor interface; (ii) a pump section configured to generate fluid flow, where the pump section comprises a pump interface having a first pump port to provide fluid flow therethrough and a second pump port to receive returning fluid flow therethrough; and (iii) an interface block coupled to the motor interface and coupled to the pump interface so as to couple the pump section to the motor section, where the interface block includes internal fluid passage to facilitate fluid communication between the pump section and the motor section.

Hydrostatic transmission

An apparatus for testing properties of materials under operating conditions of the materials. The apparatus includes a hermetically sealed vessel in which a tribology tester is mounted. The tribology tester includes a pair of lever arms having first and second ends with the first end of each lever being pivotally connected. A spring is located between the second end of each of the lever arms with a test block assembly being mounted between the lever arms in a position between the pivotal connection and the spring. The test block assembly includes a pair of test blocks and a pin with the spring biasing the test blocks into contact with the pin. Drive means, such as a motor, is magnetically coupled to the tribology tester to rotatively drive the pin against the test blocks to test the properties of the materials.
