摘要： The hydraulic multiway valve comprises a control piston (main piston 3), which is displaceable against the force of a spring (main spring 18) by the plunger of a magnet (12) from its first position (closing position) to its second position (opening position). In the closing position, a pressure chamber (7) with a pump connection (P) is closed toward a consumer chamber (8), and the consumer chamber with a consumer (A) is opened toward a return flow chamber (20) and a reservoir connection (R). In the opening position, the consumer chamber (8) is closed toward the return flow chamber (20). To this end, the consumer chamber (8) and the return flow chamber (20) are arranged at the opposite ends of the main piston (3), namely the consumer chamber (8) on the side facing the magnet, and the return flow chamber (20) on the side facing away therefrom. A central channel (21) extends through the main piston. The central channel interconnects the consumer chamber (8) and the return flow chamber (20). A magnet plunger acts upon a plunger piston, which is displaceable in the valve housing in coaxial relationship with the main piston, and which comprises a seat end facing the main piston (3), through which it closes the central channel, when it contacts the main piston. A power control unit recognizes errors in the operation of the magnet and the valve, and further insures that adequate holding forces act upon the main piston and power use to operate the valve is minimized.

摘要： A hydraulic pressure sensor for measuring the pressure in a hydraulic pressure chamber 1. A reservoir housing 9 is connected to the pressure chamber, and the interior of the housing is divided by a slideable partition 13 which defines a reservoir chamber 8 which is connected to the pressure chamber and a sensor chamber 7 which is connected to a sensor element 5. The partition 13 is constructed as a piston and extends for sliding movement along the walls of the reservoir housing while exerting a frictional force. A spring 11 supports the partition relative to the reservoir housing against the pressure in the reservoir chamber 8. The partition 13 may be constructed as a differential piston, and consist of two or more piston sections 13.1, 13.2, 13.3, which extend independently of one another in a sliding and sealing manner, and mutually support one another by an intermediate spring 14.

摘要： A check valve arrangement for a hydraulic consumer which permits connecting the hydraulic consumer selectively to a medium pressure line or a high pressure line. The valve arrangement comprises a medium pressure switching valve 10, a high pressure switching valve 14, and a check valve 6 downstream of these valves. The check valve 6 is constructed as a combined sliding and seat valve and comprises control surfaces 28, 29, 38 for the medium pressure P1, the high pressure P2, and the pressure applied to a consumer line 5, i.e., the pressure applied to the hydraulic consumer. The control surfaces are dimensioned such that a connection of the hydraulic consumer to the high pressure line can occur only when a predetermined limit pressure is reached in the hydraulic consumer.

摘要： A mining control system for adjusting the advance of the working tools of a mining machine with respect to working depth and/or working height connects to a detection device that is for recognizing the rock being mined and is carried along by the mining machine. A central command station connects by radio to the detection device of the mining machine. The mining control system comprises a plurality of radio receivers arranged in spaced relationship along the longwall, as well as a comparator, which is used for comparing the intensity of the radio signals received by the individual radio receivers and for retransmitting only the strongest of the radio signals to the central command station for generating the command signals for controlling the advance of the mining tools. It is also possible to transmit the radio signals received by each radio receiver to adjacent radio receivers. A separate comparator is associated to and controls each radio receiver. A radio receiver is allowed to transmit data to the command station only when the signals received by it are stronger than the radio signals received by the other radio receivers.

摘要： An electro-hydraulic control system for a mineral mining installation has a plurality of control units (4) sub-divided into operational groups (I, II, III) with associated roof supports. Each group has its own power source (5) and power at an intrinsically safe level is provided to each of the groups independently of and in isolation from the other groups. The control units (4) are interconnected via a system data bus (13,14) in the form of conductors of multi-core cables which also carry the electrical power. A further data bus (20) independent of the system bus (13,14) is coupled to some of the units of the groups.

摘要： A pressure-relief hydraulic valve device for mining equipment is composed of a hollow sleeve mounting a guide with a through bore slidably receiving the stem of a valve member. The stem is provided with a blind axial bore leading to a set of radial bores and a seal in the bore of the guide co-operates with the radial bores to form a valve. A spring accommodated in the sleeve acts through a shaped pressure member to urge the valve member to a position with the valve closed. Pressure fluid in equipment to be protected acts on the valve member and excess pressure displaces the valve member against the spring force to open the valve and permit the escape of fluid via an outflow chamber and outlets in the sleeve. The pressure member has a piston like flange guided within the sleeve against which the spring bears and the underside of the flange of the pressure member is shaped to provide a concave guide face in the outflow chamber.

摘要： A gearing unit has an input shaft coupled via a gear train and a clutch to an output shaft which can propel a drive chain for a mineral winning machine or plough.The clutch is released by hydraulic pressure and a load sensor operates a valve device to release the clutch should an excessive load occur. The response of the hydraulic system is optimised by using a special fast-switching valve device and by maintaining a certain pressure in a release chamber of the clutch by circulating pressure fluid through the valve device when the clutch connects the drive to the output shaft. This pressure is lower than that necessary to release the clutch and the valve device rapidly switches to increase the pressure should an overload occur.
