Solenoid valve for adjusting hydraulic pressure flow

摘要

The arrangement has a valve seat (104) within a valve body, separating two chambers, whereby the first chamber is connected over an aperture (100) formed at the valve seat with the second chamber. Devices are provided for controlling the hydraulic pressure flow which is led from the second chamber into the first chamber, and over the first aperture to the first passage, to prevent an abrupt increase of the hydraulic pressure. The arrangement comprises a valve body (74) with a first aperture (88) which is connected with a first passage (120), and a second aperture (115) which is connected with a second passage (106). The valve body comprises a first chamber (90) which is connected over the first aperture with the first passage, and a second chamber (98, 109) which is connected over the second aperture with the second passage. A valve seat (104) is arranged in the valve body for the separating of the first chamber from the second chamber, whereby the first chamber is connected over an aperture (100) formed at the valve seat with the second chamber. Devices are provided for controlling an opening and closing of the aperture of the valve seat. Devices are provided for controlling the hydraulic pressure flow which is led from the second chamber into the first chamber, and over the first aperture to the first passage, to prevent an abrupt increase of the hydraulic pressure.
