Abstract
A device for testing a hydraulic circuit including the actuating cylinder and piston therefor. The testing device comprises a unitary assembly which is adapted to be clamped to the cylinder to be tested and which actuates the piston for pressurizing the associated hydraulic circuit. Sensing elements are incorporated for sensing the pressure applied to the hydraulic circuit and for sensing the amount of travel of the piston of the actuator during a given time period. In this way leaks or flaws in the hydraulic system may be readily detected.
Claims14
A testing device for a force generating device comprising a supporting housing adapted to be fixed against movement relative to the device, a force applying portion supported for movement by said supporting housing into engagement with the device, power means within said housing for moving said force applying portion relative to said supporting portion for applying a force to the device, distance sensing means within said housing for sensing the distance of travel of said force applying portion relative to the supporting housing and force sensing means carried by said housing for sensing the force applied to said device.
A testing device for testing master cylinders and associated hydraulic circuits comprising a supporting housing, clamping means carried by said supporting housing and actuable between a released position and a clamping position for affixing said supporting housing to the master cylinder to be tested, a force applying force device carried by said housing and adapted to engage the actuating element of the master cylinder for pressurizing the master cylinder and its hydraulic circuit upon actuation of said force applying device, distance sensing means carried by said housing for sensing the degree of movement of said force applying device, power means carried by said housing for actuating said force applying device and applying pressure to the actuating element of the master cylinder, and a force sensing device carried by said housing for sensing the force generated by said power means.
