Said valve acting so that if the load sensing flow sharing elements (E3, E4) fed by the line (P2) designed for the connection with the pump (PB) are in saturation, it withdraws from the carry over (6) of the group of elements (E1, E2) of the crossing type the amount of flow rate equal to the difference between the flow rate required by the utilities (U) of the elements (E3, E4) and the maximum flow rate which can be supplied by the LS pump (PB); otherwise, it freely delivers the flow rate of the constant displacement pump to the low pressure line.
A distributor (3) of the closed-center, load sensing type, connected to a variable displacement pump (1) comprises a valve device (10, 110), composed of a logic element, which is pilot-operated and configured to bring a high-pressure channel (2) into communication with a low-pressure channel (4), the connection being usually opened by the combined action of an equivalent pressure generated by an elastic member (12) and a counter-pressure which is generated, under operative conditions, in the low-pressure channel (4). The connection is closed in a switching position and it is pilot-operated to a closure position by the combined action of a high-pressure signal (P) and a load sensing signal (LS).

B4); of which one or more elements (E1 E2) are of the CA type while one or more elements are of LS flow sharing type (E3, E4).

Said valve acting so that if the load sensing flow sharing elements (E3, E4) fed by the line (P2) designed for the connection with the pump (PB) are in saturation, it withdraws from the carry over (6) of the group of elements (E1, E2) of the crossing type the amount of flow rate equal to the difference between the flow rate required by the utilities (U) of the elements (E3, E4) and the maximum flow rate which can be supplied by the LS pump (PB); otherwise, it freely delivers the flow rate of the constant displacement pump to the low pressure line.
Modular directional valve with two or more crossing elements (E1.. En) able, acting only on the entry side, to manage a variable displacement pump (PA) of the load sensing type. In particular, this management allows in a single drive, unlike the conventional crossing distributors, to make the flow rate to the utility independent of the load and allows setting a maximum flow rate at the end of the stroke; in multiple drives, it ensures that the sum of the required flow rates is independent of the loads. A compensated flow rate regulator is placed in the entry side so as to act only on the bypass line LC upstream of the first element (E1...En) while a proportional choke is placed on the load line consisting of a 2-way 2-position tray.

A nozzle for use in a high pressure water jetting system is provided including a stationary housing, a rotating shaft, and a central passage within the shaft for communicating high pressure fluid to the nozzle. The shaft may include communication passages to provide fluid from the central passage to a forward fluid pressure chamber defined between an outer peripheral surface of the shaft and the housing. A rear fluid pressure chamber may be defined between the shaft and the housing and a restriction may be defined between the housing and the inlet end of the shaft, the restriction configured to receive fluid from the rear fluid pressure chamber and transport it to a chamber communicating with the atmosphere. The restriction may be formed as an annular gap between the housing and the inlet end of the shaft and configured to decrease in volume when the shaft moves axially forward.
