AI Technical Summary

Benefits of technology

It describes two methods used when changing fluids (liquid) flow systems: 1) continuously; 2) alternating between them. These techniques aim to reduce variations in pressures caused by changes made while making it work. They also involve coordinately switching between different types of devices based upon how fast the change needs to happen. By doing these things together, the technical effect of the inventors' design helps maintain stable operation even under high-pressure conditions without causing damage.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the performance and efficiency of sprayers used in building materials machining processes while minimising environmental impacts associated with their usage. Current methods involve injecting liquid onto the workpiece being worked upon without any consideration given how much each volume of fluid needs to be supplied throughout the whole operating period. Additionally, current systems have limitations in delivering precise amounts of liquid or powder based treatment products due to variations in the concentration levels caused by factors like temperature changes and moisture content.

Embodiment Construction

[0033]FIG. 1 relates to a construction machine 1, specifically in FIG. 1 a so-called stabilizer or a recycler, which depends on the respective application. The construction machine 1 comprises a machine frame 2, a pair of front wheels 3 and a pair of rear wheels 4, with merely the wheel disposed in the working direction a on the left side being visible. The machine frame 2 has a two-element configuration comprising two frame elements which are connected with each other by a knee-joint connection 5. A driver's cabin 6 is arranged at the level of the knee-joint connection 5, which cabin is height-adjustable along the direction of arrow b. The required drive power is provided by means of a drive apparatus 7 which provides the drive power required both for driving the construction machine 1 and for driving the working device which will be explained below in closer detail. The construction machine 1 is used for processing ground or road surfaces and the working device comprises a working ro
