Title: Roland Stig Henriksson: Innovator in Hydraulic Impact Mechanisms

Introduction

Roland Stig Henriksson is a notable inventor based in Nacka, Sweden. He has made significant contributions to the field of hydraulic technology, particularly with his innovative designs that enhance the efficiency and functionality of hydraulic systems.

Latest Patents

Henriksson holds a patent for a hydraulic impact mechanism. This mechanism features a housing with a cylinder bore, a forward working chamber, and a rear working chamber. It includes a hydraulic fluid supply passage connected to the forward working chamber and a drain passage connected to the rear working chamber. A hammer piston is reciprocally guided in the cylinder bore to deliver blows to a working implement attached to the housing. The design also incorporates a pressure accumulator pre-loaded to a certain pressure level and a distribution valve for alternatingly connecting the rear working chamber to the supply passage and the drain passage. This innovative mechanism ensures that the resulting forward-directed force prevents the piston from moving backward in the cylinder bore at pressure levels below the pre-load pressure level of the accumulator.
