    Abstract: An apparatus and method for creating vibration of an appendage of a work vehicle is disclosed. The apparatus includes a hydraulic cylinder, first and second valve assemblies, and a control element. The hydraulic cylinder is coupled between a first portion of the work vehicle and the appendage and includes a first chamber, a second chamber, and a piston. The first and second valve assemblies respectively govern whether hydraulic fluid is provided from a pump to, or to a tank from, the first and second chambers. The control element automatically causes a status of the second valve assembly to repeatedly alternate with time so that the vibration occurs at the piston and is in turn provided to the appendage.

    Abstract: In a material working (e.g. penetrating, loading, compacting) machine the power and machine weight needed to achieve a given performance can be reduced by making one (50) of two pivots (34, 50) at which a working implement such as a bucket 14 is supported an eccentric pivot and driving it by means of a motor (36). The circular vibration of the bucket at pivot (50) combined with arcuate vibration which results and is permitted at pivot (34) by means of link (30), causes the working portion namely bucket teeth (56), to vibrate on a closed elongate curved path 58. This improves penetration and loading performance of the bucket without requiring excessive power to generate the vibrations.

    Abstract: A fluid operated reciprocatable device has an outer, usually fixed, membernd an inner relatively movable member joined by a resilient member e.g., of rubber. The outer member is closed at one end so as to form an enclosure into which fluid under pressure can be admitted so as to displace the inner member in a given axial direction relative to the outer member. When a pulsating pressure is applied to the fluid the inner member vibrates axially in accordance with the pulses. The resilient member is proportioned so that its dimension in the axial direction is large in comparison with the thickness between the outer and inner members, e.g. 4 times larger. The properties of the resilient member are chosen so that it acts not only as a seal between the outer and inner members to contain fluid, but as a return spring whereby the inner member is returned, between fluid pulses, from an axially displaced position.

    Abstract: A system and method for controlling shakability of a work tool. A series of input commands from a control unit to the hydraulic pump cause the hydraulic pump to cycle between a first displacement (maximum) at a first rate (maximum) and a second displacement (zero) at a second rate (less than maximum), within a predetermined frequency. Ultimately, the hydraulic pump remains in a partially upstroked position at the beginning of every cycle. Accordingly, within a small fraction of time after upstroking, the pump is capable of providing full flow to the actuators, resulting in much faster response and movement of the actuators, and therefore improved shakability of the work implement.
