Title: Innovations of Thomas Lilja in Pneumatic Technology

Introduction

Thomas Lilja is a notable inventor based in Kalmar, Sweden. He has made significant contributions to the field of pneumatic technology, particularly through his innovative designs in drill hammers. With a total of two patents to his name, Lilja's work showcases his expertise and commitment to advancing drilling technology.

Latest Patents

Lilja's latest patents include a pneumatic drill hammer comprising a boost chamber and a drilling rig that utilizes such a drill hammer. This invention relates to a pneumatically operated drill hammer, which features a piston and a distributor arranged axially within a housing. The piston is designed to move axially between a first and a second position. The drill hammer incorporates a pneumatic drive system that consists of a drive chamber, a return chamber, and multiple channels for distributing drive gas. The return chamber is located beneath the piston, while the drive chamber is positioned above it, defined by a variable space enclosed by the housing, piston, and distributor. The drive chamber is equipped with at least one inlet port and one exhaust port located around its circumference.

Another patent by Lilja pertains to a pneumatic hammer device and a method related to it. This pneumatic hammer includes a connector for linking to an external compressed air source and features a striking mechanism. The striking mechanism consists of a housing and a piston that moves reciprocally within it. The piston has front and rear portions, creating front and rear spaces within the housing. A compressed air conduit is in airflow communication with the front space through a second passage in the housing, where a first valve is installed. An intermediate space exists between the piston portions and the housing, allowing the control unit to alternate air pressure between the rear space and the intermediate space during the piston’s reciprocating motion. This control unit manages the first valve based on air pressure to alternately supply compressed air to the front space, facilitating the return movement of the piston.
