Abstract: A dashpot for wheel suspensions, with a preferably sheet-metal spring cup (6). The cup is attached to a shock absorber or its accommodating tube, supports a helical spring that surrounds the shock absorber or tube, and can be advanced along the shock absorber or tube on threads. To allow the dashpot to be raised and lowered in precise increments, the attachment is maintained tight by a cylindrical housing (3). The housing is provided with a slot extending over its total length and with outside threads. Its inner surface of the housing rests directly against the shock absorber or its tube. The housing operates in conjunction with a height-adjustment ring (12) or neck (7) with matching inside threads on the spring cup. The slope of the threads ensure that the force exerted by the spring on the spring cup will squeeze the slotted housing together radially.

Since the spring seat (7) is integrated with an adjuster (10) by engaging claws (9) with the adjuster (10) and is also integrated with a movable cover (20), the spring seat (7), the adjuster (10) and the movable cover (20) rotate and move to an axial direction as one body.

Abstract: A motor brake apparatus includes an improved torque adjustment mechanism. The adjustment mechanism includes an adjusting nut having a outer ring groove aligned with an inner ring groove defined in a receiving bore of the brake housing structure. A snap ring is located in the aligned grooves to connect the housing structure and adjusting ring while allowing free rotation therebetween. Inner threads of the adjusting nut engage outer threads of a spring pushing element such that rotation of the adjusting nut causes axial movement of the pushing element. The pushing element engages one or more springs which are thereby compressed or released, depending on which axial direction the pushing element is moved. The spring force varied in this manner results in varying levels of braking torque.

Abstract: An injection valve, which overcomes residual magnetic forces and cohesive forces that act between the armature and the core to make the armature stick to the core, impeding the closing motion of the valve needle. The injection valve has a spring adjusting sleeve and a stroke adjusting sleeve for the separate adjustment of the spring force of a restoring spring and of the stroke of the valve needle: these sleeves are disposed in a through bore of a valve end cap. The stroke of the valve needle is limited by a downstream end face of the stroke adjusting sleeve, which when the injection valve is fully open rests on an upstream face end of a fastening segment of the valve needle. A remanent air gap is left between the armature and the core. The novel injection valve is especially suitable for fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

Abstract: A lock assembly allows selective locking of a refuse container so that it cannot be manually opened by an unauthorized user, but can be opened automatically by a refuse collection truck when the container is to be emptied. The lock assembly has a locking bar that is attached to a control bar which is pivotally mounted to the refuse container. In one embodiment, the control bar is selectively connected to a spring such that when the container is to be locked, the control bar and locking bar are connected to the spring by a lock and in order to open the container the bias of the spring must be overcome. The spring is set such that this bias is easily overcome by engagement of the coupler of a refuse collection truck. When the lock is removed, the control bar is separated from the spring and the locking bar freely rotates. In another embodiment, the locking bar is connected to a spring bias control bar by articulated connecting members.

Abstract: A regulator with a hysteresis-affected characteristic curve has a manually operable actuating element for presetting a desired control variable, an axially displaceable control slide for adjusting the preset control variable and a control incline which is coupled to the actuating element. The control incline converts, by means of a rising control face, the adjustment movement of the actuating element into a axial displacement of the control slide. For the purpose of compensating the hysteresis when adjusting a control a variable such that the same control variable is brought about by rotating the actuating element to the left or to the right into the same setting, the control incline bears a toothing along its control face. Each tooth has, in two planes which extend along the displacement direction of the control face and are perpendicular to one another, a sawtooth-like contour with in each case a rising edge for running up the control slide and a falling edge which follows in the displacement direction.

In a second position, the adjustment subassembly relieves the biasing force exerted on the mounting plates, thus allowing movement of the movable roll away from the other roll to accommodate passage of a mass of material therethrough. A system is provided for interconnecting the adjustment subassembly with a lifting and lowering system for the conditioner.

The extension spring mechanism comprises a pair of parallel, spaced-apart extension springs, the axes of which are parallel to the axes of the base, collar, and guide tube and normally biases the collar and the guide tube in their extended positions. The extension springs are in a retracted condition. Thus, when force is exerted on the top of the guide tube, the extension springs assume an extended condition.

Abstract: A pressure adjustment screw for a fluid flow control device cannot for safety's sake be rotated within a threaded cylindrical bore on the device's body to withdraw it beyond an extreme pressure level safety setting.

The U-shaped ramp plate is inserted between coils of the spring to surround the central, shock absorber stem. Then when the device is rotated, the ramp plate is threaded down the coil spring to pull it up into the containment between the tie bars. The slight compression of the coil spring in this manner relieves force against the spring mounting to enable repair and or change of the shock absorber.

The indicating member is in engagement with the handle whereby rotation of the handle results in simultaneous axial movement of the follower and the indicator member. The indicator member includes visually observable means for indicating the relative degree of compression of the spring.
