Dear Colleagues,

Hydrostatic systems are still some of the main and leading types of power transmission in various types of devices and machinery, both stationary and mobile. The basic components of hydrostatic drive systems are positive displacement pumps, motors, and any types or elements (valves) of control systems. The efficiency of a hydrostatic system is affected by the efficiency of its individual components, i.e., both pumps, motors, and valves. Therefore, there is a need to constantly improve the efficiency of these components.

Therefore, the already-known designs of positive displacement machines and valves are analyzed, and completely new designs are designed and developed, taking into account the latest materials and manufacturing techniques.

Particular attention should be paid to components that can be used to build hydrostatic systems dedicated to working with environmentally friendly liquids, including water.

The contributions may be focused on one or more of the following topics:

• a methodology for the design of positive displacement pumps, motors, and valves;
• a description of the phenomena of pumps, motors, and valves;
• the modelling, operation, and simulation of pumps, motors, and valves;
• the influence of working liquid types (including eco-liquids and water) on the efficiency of pumps, motors, and valves;
• experimental research results of pumps, motors, valves, or their components;
• new materials used in the construction of pumps, motors, and valves, and their impact on the efficiency of these components;
• new technologies for manufacturing pump, motor, and valve components, and their impact on the efficiency of these components;
• assessment of the state of vibration and noise emission of hydraulic components.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Machines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
