The invention relates to a spring-damper element (2) for mounting a punching press (1), with a hydraulic damper unit (3) with a first fluid chamber (4) and a second fluid chamber (5), wherein, in the intended operation, a hydraulic fluid is displaced from the first fluid chamber (4) via a throttle point (6) into the second fluid chamber (5) when the spring-damper element (2) is compressed. The damper unit further comprises an overload valve (7) arranged between the first fluid chamber (4) and the second fluid chamber (5), which overload valve opens when a specific fluid pressure is reached in the first fluid chamber (4) or when a specific pressure difference is reached between the first fluid chamber (4) and the second fluid chamber (5) and releases a bypass (8) via which hydraulic fluid then flows from the first fluid chamber (4) into the second fluid chamber (5) bypassing the throttle point (6). Thereby, the spring-damper element (2) is designed in such a way that the fluid pressure or the pressure difference, respectively, at which the overload valve (7) opens can be adjusted when the spring-damper element (2) is installed as intended. With such spring-damper elements according to the invention, it becomes possible to create a mounting arrangement for a punching press, the damping characteristics of which can be adjusted without significant effort, such that a variable operation of the press in wide ranges becomes possible while keeping the ground loading to a minimum in each case.

A dispensing pump includes a spring assembly and a locking arrangement to prevent the dispensing head from being deployed and/or actuated during shipment, stocking and pre-purchase handling.

A loading skip box (14) is installed at the top of a large-tonnage skip (12), a coal dropping buffer device (13) is arranged on the inner sidewall of the large-tonnage skip (12), and the coal dropping buffer device (13) includes: a frame (1) fixedly connected with the inner sidewall of the large-tonnage skip (12); a lining plate guide frame (6) connected with the frame (1) through shock absorbers (2), guide sliding grooves being formed in the lining plate guide frame (6); a lining plate support (4) slidably nested in the guide sliding grooves in the lining plate guide frame (6), hoisting lugs (9) for hoisting being arranged at the top end of the lining plate support (4); and a lining plate (5) detachably connected with the lining plate support (4) through fasteners (7).

A cab mount for attaching a frame to a body is provided to prevent a forcible movement of the body generated under the influence of vertical vibration of the frame. A first cab mount includes: a collar extending vertically; and an upper mount rubber and a lower mount rubber disposed to face in the upper-lower direction on an outer periphery of the collar. The collar is attached to a body of a vehicle by being inserted into an attachment hole of a ladder frame of the vehicle while a peripheral part of the attachment hole is positioned between the upper mount rubber and the lower mount rubber. The upper mount rubber is spaced apart from the ladder frame in the upper-lower direction by a first predetermined distance while the lower mount rubber is spaced apart from the ladder frame in the upper-lower direction by a second predetermined distance.

A suspension damper for washing machines includes a control rod that is configured to attach a fixed bracket of a washing machine cabinet and a first cap having an aperture through which the control rod slidingly extends. The first cap is configured to engage a concave portion of a bracket on a drum of the washing machine. A second cap is disposed on the control rod, and a spring is disposed between the first cap and the second cap. The first cap includes at least one water passageway for guiding water along an outer surface of the first cap. An umbrella may be disposed on the control rod to shed water outwardly away from the control rod.

To increase a compactness of damping systems intended to operate in the event of a dynamic landing of an aircraft, a damping system comprises a primary damper device and a secondary damper device. The primary damper device comprises at least one beam, each beam extending along a direction of a longitudinal axis. The damping system is configured so that at rest, the primary damper device has a stiffness greater than a stiffness of the secondary damper device in the direction of the longitudinal axis. When a force is applied to the damping system along the direction of the longitudinal axis, with a value less than a limit value, each beam remains in a compression state. When the force applied has a value greater than or equal to the limit value, each beam undergoes buckling and the secondary damper device undergoes elastic deformation.

An elastomeric compression spring for isolating vibrations between a first part and a second part. The first part is movable in a direction relative to the second part. The elastomeric compression spring comprises a tube elongated along a central axis of the tube. The central axis of the tube is perpendicular to the direction. The tube is configured to compress in the direction. The tube comprises an outer surface comprising an initial contact line configured to initially receive contact from the first part. The tube further comprises at least one load tuning feature in the outer surface, parallel to the central axis, and circumferentially spaced apart from the initial contact line. The at least one load tuning feature creates a localized change in a thickness of the tube and a stiffness of the elastomeric compression spring at the at least one load tuning feature.

A shock isolator assembly comprises a base a platform and a plurality of self-resetting buckling isolators providing a three-stage response to a dynamic load acting between the base and the platform. The three-stage response of the self-resetting buckling isolators comprises a tension stage when the dynamic load exceeds a threshold tension load, a compression stage when the dynamic load exceeds a threshold compression load, and a rigid stage when the dynamic load is below the threshold tension load and the threshold compression load.
