摘要： The invention aims at bringing about a device for remote controlling of, for example, directional valves, which likewise allows a manual direct controlling, using a hand lever, for example. The control device includes a hydraulic cylinder (37) with ports (31,32) for feeding and evacuating, respectively, of hydraulic fluid, a piston (14) arranged in the cylinder (37), as well as a piston rod (13), for accomplishing the controlling function. The piston rod (13) is arranged to be slideably supported in the piston (14), allowing a limited movement of the piston rod (13) relative to the piston (14) independent of the pressure and load conditions in the cylinder (37), the movement possibility of the piston rod (13) being limited in at least one direction by a stop (17) arranged on the piston rod.

摘要： Device in a hydraulic power system connected to a load driving hydraulic motor (18; 32), comprising a pilot controlled flow regulating directional valve (1; 29) for alternative connection of the service ports of the motor (18; 32) to a pressure medium source and a tank. The directional valve (1; 29) comprises two opposite and by a pilot pressure activatable activating means (3, 4), and a pilot pressure means (84) is arranged to pressurize and activate the activating means (3, 4), alternatively, and drain one of the activating means to the tank through a flow restriction (5, 7) at activation of the other activating means (3, 4). The power system comprises at least one control flow circuit (10-12; 72-83; 37-44) which communicates with one of the activating means (3, 4), and a valve means (11, 12; 71; 31) which is arranged to accomplish a flow through the control flow circuit (10-12; 72-83; 37-44) in relation to the load pressure on the motor such that the counter pressure from the flow restriction (5, 7) generates a compensating force in relation to the load pressure on the motor on the non-activated activating means (3, 4).

摘要： A method and apparatus for insulating a spray liquid source from the high tension voltage of an electrostatic spray gun (13) when using an electrically conductive spray liquid. A spray liquid supply line (12) couples the spray liquid source to the spray gun and comprises an insulating device (14) in the form of a closed vessel (16; 26; 36) containing an electrically non-conductive liquid which is not mixable with the spray liquid and which has a density different from that of the spray liquid. A sprinkler nozzle (21; 31; 41) is arranged to disintegrate the spray liquid into separated drops which are transported through the insulating liquid (17; 27; 35) in the closed vessel at least by the influence of the difference in gravity acting on the two liquids. The separated spray liquid drops form a discontinuation of the electrical lead through which the high tension voltage propagates upstream through the supply line. Thereby, the parts of the supply line upstream of the insulating device, which may include a spray liquid feed pump (11) and a spray liquid receptacle (10), are electrically insulated from the high tension voltage. The closed vessel (26; 36) of the insulating device may comprise passages (27, 28; 37, 38) and a pump (30;40) to forcibly circulate the insulating liquid within the passage in the closed vessel such that a movement is superimposed upon the gravity influenced spray liquid transportation movement to increase the spray liquid flow capacity through the insulating device.

摘要： A hydraulic torque impulse generator comprising a rotationally driven drive member (10; 50), a hydraulic fluid chamber (16; 51) confined in the drive member (10; 50), an output spindle (18; 53) having a rear impulse receiving portion (17; 52) extending into the fluid chamber (16; 51), at least two radially slidable vanes (23, 24; 58, 60) carried by the rear spindle portion (17; 52) and cooperating with corresponding seal portions (25, 26; 62, 63, 64) on the fluid chamber wall, axially extending seal ribs (29, 30; 65, 66, 67) on the fluid chamber wall and corresponding axially extending seal ribs (27, 28; 68, 70) on the rear spindle portion (17; 52). Simultaneous sealing cooperation is obtained more than once during each revolution of the drive member (10; 50) relative to the output spindle (18; 52), whereby the fluid chamber (16; 51) is momentarily divided into at least two high pressure compartments (H.P.) and at least two low pressure compartments (L.P.). A first passage mechanism (32-35; 74-78 ) in the drive member (10; 50) cooperates with a second passage mechanism (37, 38; 73) in the output spindle (18;53) to form bypass passages between the high pressure compartments (H.P.) and the low pressure compartments (L.P.) in all but one of the fluid chamber dividing positions, such that only one torque impulse per relative revolution between the drive member (10; 50) and the output spindle (18; 53) is generated.

摘要： A marking device for automatic marking of threaded joints tightened by a pneumatic power wrench, wherein a marking liquid container (48), a metering pump (37), a pressure air supply valve (31) and a marking liquid outlet passage (55) form a unit detachably clamped onto the power wrench housing (10). Pressure air communication passages (24, 25) feed the marking device directly with pressure air from the air supply passage (13) of the power wrench. The marking liquid container (48) comprises a replaceable collapsible tube which is pressurized all around in a pressure air supplied chamber (28). The single stroke metering pump (37) delivers for each stroke a well defined quantity of marking liquid to the outlet passage (55) which is formed by a fine hose made of plastic material with non-adhesive properties relative to the marking liquid. A pressure air operated feed valve (62) is arranged to prevent back flow and other uncontrolled flow of marking liquid through the outlet hose (55) by compressing the latter.

摘要： A tandem piston arrangement for a compressor, especially for a dry-running compressor for the high pressure compression of gases such as oxygen, has one piston of the common rod form as a guide piston with piston and guide rings in engagement with the respective cylinder, and at least one other piston as a contactless piston. By thus moving the guide point of the rod with the contactless piston, the length of any vibratile portion of the rod carrying the contactless piston remains constant during reciprocation of the assembly and the vibratile natural frequency thus does not change during operation.
