Experimental Research Results of the Slot Seal Constructed as Hydrodiode for the Hybrid Power Piston Volumetric Machine

The aim is to present the experimental studies results of the annular piston slot seal constructed in the hydrodiode form. This seal was considered in relation to the piston hybrid machine of volumetric operation. The paper describes the experimental test-bench, a node of load-registration and a hydrodiode node. The progress of the pilot studies has been described. Also some experimental results are presented in the paper. They allow to compare the numerical and field experiments findings and to conduct the slot seal initial geometry optimization, to make recommendations for the further design and construction of hybrid power piston volumetric machines.
