摘要： An insert or cartridge that fits into a cavity in a valve body provides a check valve function and an anti-cavitation function and a pressure relief function. This insert is substantially circular and has an internal cavity with a valve assembly that has two pairs of valve seats, one pair of valve seats providing the anti-cavitation function and the other pair of valve seats providing the pressure relief function. The outside of the insert itself engages with a sealing surface in the cavity in the valve body to provide the check valve function.

摘要： The present invention concerns a method for controlling the speed of motion of a hydraulically operated machine, an operating system and a control device of the machine. The flow line (3) of the medium from the pump (2) to the machine (1) is divided into two branches (10, 11). By means of a valve (8), the second branch (11) can be set to feed medium either to the machine (1) or to return the medium to the tank (4) of the pump. Such a flow is led to the second valve (8), that at a speed of rotation of the pump lower than the highest speed of rotation, the difference between the flow supplied by the pump and the flow through the second branch produces the desired slowest speed on motion of the device. When the valve (8) is set to return the medium to the tank (4) of the pump, the flow from the pump (2) is adjusted by changing the speed of rotation of the pump.

摘要： A speed controller has a pilot check valve having a first body which has a first fluid inlet/outlet port defined in an end thereof and a pilot port defined in an opposite end thereof. A flow control valve has a second body integral with the first body. A pipe joint has a third body which has a second fluid inlet/outlet port defined in an end thereof and, the third body being integral with the second body. A flow adjustment screw is disposed in the flow control valve and extends into a fluid passage which interconnects the first fluid inlet/outlet port and the second fluid inlet/outlet port, for adjusting a rate of flow of a fluid under pressure in the fluid passage. A valve body is disposed in the pilot check valve for opening a fluid passage which interconnects the first fluid inlet/outlet port and the second fluid inlet/outlet port in response to a pilot fluid pressure supplied from the pilot port.
