Thermostatic valve for connecting an automatic transmission with an oil cooler
First Claim
1. A thermostatic valve for connecting an automatic transmission with an oil cooler, having a first inlet conduit (12) for oil received from the transmission, a first outlet conduit (13) for oil delivered to the oil cooler, a second inlet conduit (14) for oil received from the oil cooler, and a second outlet conduit (15) for oil delivered to the transmission, wherein a connection between the first inlet conduit for oil received from the transmission and the first outlet conduit for oil delivered to the oil cooler is opened or blocked by means of a valve element (22) which is actuated by a thermostatic actuating element (16, 17) and is spring-loaded by means of a restoring spring (21), characterized in that the valve element (22) with the restoring spring (21) comprises a pressure-control valve positionable in a release position when the connection is open between the first inlet conduit (12) for oil received from the transmission and the first outlet conduit (13) for oil delivered to the oil cooler to open a bypass conduit (24) between the first inlet conduit (12) for oil received from the transmission and the second outlet conduit (15) for oil delivered to the transmission when a predetermined pressure of the oil is exceeded.

Abstract
In a thermostatic valve for connecting an automatic transmission with an oil cooler, wherein the connection between an inlet conduit 12 for oil coming from the transmission and an outlet conduit 13 to the oil cooler is released or blocked by means of a valve slider element 22, which is actuated by a thermostatic actuating element 16, 17 and is spring-loaded by a restoring spring 21, the valve slider element 22 with the restoring spring 21 is designed as a pressure-control valve which, with the open connection between the inlet conduit 12 for oil coming from the transmission and the outlet conduit 13 to the oil cooler, opens a bypass conduit 24 when a predetermined pressure of the oil is exceeded.
