HYDRAULIC VALVE MECHANISM

Description

The present invention relates to a hydraulic valve mechanism. The mechanism according to the present invention combines an arrangement of a suitably shaped piston, a cylinder, an electromagnet, an air chamber, ports and a suitable hydraulic circuit for distributing steam oil or pressurized air.

State of the art

Today there are many hydraulic valve mechanisms which are used in all sectors of industry, etc. The present invention combines through continuous improvements of hydraulic valves the smoothest possible operation of reciprocating piston machines or in sectors of industry. It is in this field that the present invention aims to provide.

Brief description of the invention

The mechanism according to the present invention consists of a suitably modified piston, which works inside a cylinder and through the rod of the piston a force is exerted by the electromagnet by displacing the piston in two positions we achieve the distribution of active material as the case may be in a reciprocating machine, or on a hydraulic piston that we want to move.

The present invention is described below in more detail with the help of the figure.

Shape description

Figure 1 shows: The cylinder (P), a piston (H), which is connected to one end of the piston rod (L) with an electromagnet (E), and at the other end with a spring (D). Also visible in Figure 1 are the two positions (A), (B), of the piston (H), the appropriate active material supply network (O), the air chamber (Θ), the ports (K1,2), (Σ1,2 ), the pistons (C1,2,3,4), and the crankshaft (N).

Figure 2 shows: The piston (C), the control (X), and the switches (M1,2).

Description of the invention

The hydraulic valve mechanism can be applied for the smooth operation of a reciprocating piston engine by distributing air, steam, or oil under pressure at the appropriate time by applying through the active material supply device from the chamber (Θ), through the ports (K1, 2 Σ1 ,2) and the supply pipes (O), on the pistons e.g. (C1,2,3,4), the crankshaft (N) or the piston (C) is turned through the control (X).

Description of the operating cycle of the hydraulic valve mechanism

The piston (H) as shown in Figure 1 is in its initial position (A) under the influence of the spring (D) the supply under pressure of active material from the chamber (Θ) is activated, following the arrows as shown in Figure 1 passes through the pipes (11,2,3,4) of the suitably shaped piston (H), and through the revealed port (K1), following the appropriate hydraulic circuit (O), supplies active material (e.g. air , oil, steam) to the pistons (Γ1,2,3,4) at the appropriate time so that we have smooth movement of the pistons and rotation of the crankshaft (N). In the position (A) of the piston (H) the port (K1) functions as a supply of the active material under pressure and the port (K2) as an outlet at atmospheric pressure through the groove of the piston (H) and the port (S2). When the piston (H) is under the influence of the electromagnet (E) in position (B), the former active material supply port (K1) becomes intake, and the port (K2) becomes active material supply following the arrows in Figure 1 in position (B) through port (K1) of the piston groove (H), and port (S1) depressurize to atmospheric pressure. The former port (K2), exhaust at atmospheric pressure in the position (B) of the piston (H) now becomes active material supply. When a command is given to the electromagnet (E) by interrupting the electricity supply, the above procedure is repeated.

In Figure 2 the operating principle of the hydraulic valve is the same as in Figure 1, i.e. the positions (A) and (B) of the properly configured piston (H) remain the same. Specifically in Figure 1 as mentioned above the piston (H) is moved using the electromagnet (E), while in Figure 2 it is moved with the control (X). Thus we achieve controlled positions (A), (B) of the piston (H) and movement of the piston (C) through the switches (M1,2) supplying active material. It is obvious that changes can be made in the geometry and sizes of the technical features of the invention while remaining within the scope of protection of the invention as defined by the claims.
