A handheld work apparatus includes a first assembly, a second assembly and an anti-vibration unit which includes a coil spring. A first end of the coil spring forms a fastening eyelet fixed to the first assembly by an attachment screw which extends through the fastening eyelet and the head thereof projects into the coil spring. A second end of the coil spring is screwed onto a connecting piece of the second assembly which has an opening extending through the connecting piece and through which an engagement contour in the head of the attachment screw is accessible for a tool. When the work apparatus is in a non-loaded state, the distance (f) between the fastening eyelet and a front end of the connecting piece is the length (g) of the attachment screw. The distance (p) of the above support surface from the front end of the connecting piece is the length (g).

Variable displacement pumps and biasing assemblies for the same are disclosed. Example pumps may include a housing having an inlet and an outlet, and a rotor fixed for rotation with a shaft, with the shaft rotatably mounted within the housing. The pump may further include a plurality of radially extending vanes slidably disposed in the rotor, and a pivotable ring member defining a control chamber about the rotor, with the ring member being pivotable within the housing to vary an eccentricity of the ring member with respect to the rotor. The pump may further include a biasing assembly applying a biasing force to the ring member in a first direction about the shaft, with the biasing assembly including at least one resilient element extending longitudinally along a stand, and a sliding support slidably disposed on the stand and laterally supporting the resilient element with respect to the stand.

An arcuate spring having a plurality of coils which are configured and dimensioned to provide an arcuate shape to the spring and being substantially free of internal stresses which would tend to urge the coils into linear alignment. The spring is designed to function under load conditions while maintaining its natural arcuate shape. The spring is can be heated by use of an induction heating process.

A spring assembly includes coil springs supported on a spring support member. The coil springs include plural first coil springs and a second coil spring. The spring support member includes a first support member and a second support member facing the first support member. One ends of the first coil springs are supported on a front surface of the first support member. One end of the second coil spring is supported on the front surface of the first support member or a front surface of the second support member, and in this state, another end of the second coil spring protrudes further than other ends of the first coil springs. A sum of elastic repulsive forces of the first coil springs is larger than an elastic repulsive force of the second coil spring in a state where the first coil springs and the second coil spring are compressed.

A step-down spring seat assembly secured to a vibratory screen machine is configured to receive one or more universal adapter plate assemblies, to which one or more compression springs is secured. The universal adapter plate assemblies are secured to a top surface of the step-down spring seat assembly, and one or more spring guide castings are connected to the one or more universal adapter plate assemblies. Compression springs are positioned atop the spring guide castings, and are secured to a top adapter plate assembly that is connected to one or more universal adapter plate assemblies positioned above the one or more compression springs.

The present invention is provided focusing on a servo press configured to enable high-speed/high-accuracy operation by numeric value control in the method for manufacturing an arc-shaped coil spring. The present invention provides a manufacturing method and a manufacturing device configured so that the curvature of the arc-shaped coil spring can be freely ensured. The manufacturing method includes the clamp step of fixing a straight cylindrical coil spring, the end portion detection step of detecting an end portion, a rotation angle position determination step, a pitch feeding step, a pressing member insertion step, and an insertion direction conversion step. The manufacturing method and the manufacturing device relate to the technology of continuously repeating the operation of pushing down a pressing member to an inter-pitch from above, thereby deforming the straight cylindrical coil spring into the coil spring with the curvature.

Disclosed is a method for producing a rod antenna for a vehicle, wherein a coil spring (10) is connected on at least one of its two ends to an antenna component, and wherein the connection between the coil spring (10) and the antenna component is established by expanding the inner diameter of the coil spring (10), by at least partially sliding the antenna component into the expanded coil spring (10), and by subsequently returning the coil spring towards the original inner diameter for securing purposes. The invention is characterized in that a wire (18) is inserted into the intermediate region between the coil spring (10) and the antenna component when the coil spring (10) is expanded.

The disclosed technology relates to features provided on a lawn care vehicle. One of the features relates a spring tension assembly incorporated into a deck lift assembly. The spring tension assembly includes a spring body having a plurality of coils along a longitudinal axis between a first end and a second end. The second end of the spring body is configured to define a female threaded portion, which is threadedly engaged by a threaded fastener. Another feature relates to a lawn care vehicle hood assembly that can be assembled in a substantially tool-less manner. Another feature relates to a muffler assembly including a muffler body and a muffler shield assembly having a first wall positioned adjacent a first side of the muffler body and a second wall positioned adjacent a second side of the muffler body.

The disclosure relates to a linear drive for an adjustment element of a vehicle, with a drive train for generating a driving force along a geometrical drive axis between two coupling points, one of the coupling points comprising a joint part for discharging the driving force, which joint part, in the mounted state, forms a ball and socket joint with a mating joint part, the joint part having a bearing portion, a joining part arranged thereon and a connecting portion arranged thereon. The connecting portion serves for the connection of at least one drive train component of the linear drive to the joint part and has at least one connecting formation which is in engagement with the relevant drive train component, and wherein at least one part of the bearing portion is configured integrally together with the joining part and the connecting portion from at least one plastics material.
