Title: **Innovative Contributions of Helmut Kollotzek**
Introduction
Helmut Kollotzek, a distinguished inventor based in Mutlangen, Germany, has made significant strides in the field of piston technology. With a total of seven patents to his name, Kollotzek has demonstrated a relentless pursuit of innovation, particularly in the design and functionality of casting cores for cooling channels in pistons.
Latest Patents
Among his latest inventions, one notable patent is a casting core designed for forming a cooling channel in a piston. This soluble and substantially ring-shaped casting core incorporates a unique cooling channel featuring at least one inflow and one outflow. The innovative design allows for a closed ring configuration, with the inflow strategically positioned adjacent to the outflow. Additionally, the casting core includes a cross-sectional taper that creates a choke in the circumferential direction between these two openings.
Another significant patent relates to a casting core for producing a cooling channel that transitions into two areas, approximately parallel to the piston axis and directed away from the piston head. This inventive design includes a bending of the core, resembling a quadrant shape, facilitating an efficient transition into the feed and discharge openings of the cooling channel. By maintaining a specified distance between these two areas, which corresponds to twice the cross-sectional diameter of one of the areas, the design enhances the throughflow of cooling oil, thereby improving the overall cooling of the piston.
Career Highlights
Kollotzek has had a notable career, primarily associated with Mahle International GmbH and Mahle GmbH. His work in these reputable companies has allowed him to contribute significantly to advancements in automotive technology, particularly in the area of piston design and cooling systems.
