Abstract

Кормилна уредба с хидравличен спомагателен усилвател, по-специално за моторни превозни средства, състояща се от част на управлението, съдържаща приспособление за управление и управляем серводвигател, и от сервочаст, съдържаща привключваем серводвигател, характеризираща се с това, че за регулиране на налягането в двете нагнетателни камери на привключваемия серводвигател са предвидени два действуващи като хидравлична везна сервовключвателни вентила, всеки от които има централен разпределителен канал, свързващ захранваща връзка, респ. Отвеждаща връзка, с нагнетателната камера на привключваемия серводвигател, при което едната разпределителна повърхнина на съответното бутало на всеки вентил е свързана със съответен тръбопровод за хидравличната течност, водещ към едната, респ. Към другата нагнетателна камера на управляемия серводвигател, а другата разпеделителна повърхнина на съответното бутало на всеки вентил е свързана със съответен тръбопровод за хидравличната течност, водещ към едната респ. Към другата нагнетателна камера на привключваемия серводвигател. Патентните претенции са формулирани в 7 точки.Hydraulic power steering, in particular for motor vehicles, consisting of a control part containing a control device and a controllable servo motor, and a servo part containing a switchable servo motor, characterized in that for regulating the pressure in both discharge chambers of the plug-in servomotor, two servo-switching valves acting as a hydraulic balance are provided, each of which has a central distribution channel connecting a power connection, resp. A discharge connection, with the discharge chamber of the plug-in servomotor, wherein one distribution surface of the corresponding piston of each valve is connected to a corresponding conduit for the hydraulic fluid leading to one, respectively. To the other discharge chamber of the controlled servomotor, and the other distribution surface of the corresponding piston of each valve is connected with a corresponding pipeline for the hydraulic fluid leading to one resp. To the other discharge chamber of the plug-in servomotor. The patent claims are formulated in 7 points.
